I chose 6 pieces of art from my favorite aritist on Instagram. In order: 1. @arturodraws A fantastic artists who works with the Dallas Mavericks of the NBA. He created this rendition of Rodrigue Beaubois on March 27, 2024. Diminution (3/5): The rock formations do decrease in size as you move further away from the foreground, and the Golden Gate Bridge does appear smaller because it is further away. However, this piece does not seem to focus on the use of diminution because the player is huge! Convergence (4/5): The rock formations and bridge all seem to converge at a point off of the left of the canvas. The player himself converges to a different vanishing point to the right side of the canvas. I do think that the top of the bridge does not converge well to the same point, and thought that the further side of the support should be a bit higher than the closer side of the support. Overlap (5/5): Rock formations overlap one another, as well as the player in relation to the bridge. Atmosphere (4/5): My favorite part of this drawing. The left rock formations, trees in the background, and the shorts on the player are all faded to different degrees. Arturo even uses a splash of water to create a misty effect which I really love. Going to post the highlights of the rest of the pieces to keep it shorter 2. @artwithbryn My favorite part of this piece is that almost everything is faded for the atmospheric perspective. The only solid parts are parts of the swords and the pommel of the large sword. This piece is largely driven by atmosphere and overlap, with use of convergence as well. (D: 3/5) (C: 3/5) (F: 1/5) (O: 5/5) (A: 5/5) 3. @nicolasvsanchez Organic forms with very few straight lines, so not the best to study perspective, but I love his work and wanted to try! The piece wasn't rendered to be realistic and was left 'fuzzy', so it is hard to determine any atmospheric perspective. The forearm of the person holding the child shows foreshortening, and the child overlaps the person to create depth. (D: 1/5) (C: 1/5) (F: 4/5) (O: 5/5) (A: 1/5) 4. @paulheaston I love Paul's work. His videos are so soothing because he has such confidence in building out his drawings with relatively accurate perspective. I rated everything except atmosphere as a 5, because everything converges to vanishing point in the back left, objects get clearly smaller as they move away from the foreground, the objects overlap in the foreground and background to establish where they are in relation to the viewer. Atmosphere I gave a 2, because the background objects dont have hatching which gives a similar effect to fading away. Last note - first person point-of-view makes it very easy for the viewer to recognize the major parts of the drawing. (D: 5/5) (C: 5/5) (F: 5/5) (O: 5/5) (A: 2/5) 5. & 6. @flo.creates.art One of the most creative artists on instagram that preaches and teaches perspective. The first picture of the skeleton is interesting because the perspective grid is bent in a fisheye lens, but everything still works! The major focus is the foreshortening of the body starting with the shoes closest to the viewer and working its way up to the head which is tiny. (D: 4/5) (C: 5/5) (F: 5/5) (O: 3/5) (A: 0/5) The second image also is a masterclass of foreshortening, in my opinion. The perspective grid seems to be 1 point landing somewhere in the torso, not curved like the first piece. (D: 5/5) (C: 5/5) (F: 5/5) (O: 5/5) (A: 0/5)

This assignment has me feeling like the kid in the back of the class who asks the teacher "Did you collect the homework for today?". Luckily I feel like I'm in a classroom with other students excited to draw lines and circles! Thanks for the advise and challenge, Marshall. Here's a few attempts I made: some lines were accurate, most not. Regardless, I had fun practicing. I am starting to see what Peter Han said about correcting a line that isn't quite right. My biggest takeaways: I tried to stop resting my elbow/forearm on a hard surface when drawing lines. Resting on my chair's arm or the table gives me a lot of stabilization, but I do want to get better at drawing lines regardless of my environment. Pulling towards my body almost always resulted in a cleaner line, while pushing away resulted in a more gestural line, which I found interesting. Using a Helix circle is hard when you haven't tried it before! I started to get the hang of it, but definitely need more practice. Circles are my favorite shape. They are just so beautiful!

I never expected my work to be critiqued! I appreciate it a lot and thank you for your words of advice. It makes me want to practice and get better that much more!

Hi, Marshal and group! After watching this critique many times (due to my iPad spontaneously replaying videos on an opened page); I finally grasped the objective of these studies with optical illusions! I wanted to share my visual thinking and analysis based on the last shape Marshal shared (the outline one that Stepka and Mike worked on. It is a David's star rotated 90 degrees on the side, with added thickness. I elevated it from a regular square grid graph paper, which presented its own set of challenges and visual mischiefs. After playing with the shape, I have a better grasp of where we are heading with the forms.

This was awesome, thank you Marshall. I tried using my triangles during the Isometic Optical Illusion homework assignment and was struggling in a dramatic fashion (many huffs and puffs). This was a very helpful illustration that I will practice a bunch!

Finally finished this assignment. For whatever reason, isometry was not clicking in my brain. I first started by trying to make my own optical illusion, but quickly decided to transition to a study of Sandro del Prete, named 'The Crusader of the lattice fence'. I did a much simplified version, and that direction alone helped make things click. It was fun to work through the puzzle, and definitely gave me a greater appreciation for this art form and style. I learned: My pace of drawing a straight line is improving in consistency How to effectively use my triangles to keep lines parallel What I need to continue to improve: Continued proficiency with tools Shading Hand pressure control This assignment was really fun once I broke through that first barrier! Happy to get out of my comfort zone for a while, and definitely will practice again.

When doing these line exercises, I found myself in situations where I could not keep my pinky in contact with the paper due to getting close to the right edge of the page (I am a righty and really enjoy the feeling of keeping my pinky on contact with the paper). Is it ever appropriate to rotate your canvas so you can keep contact with the page? Of course, these are just lines with no consequence other than improving muscle memory, but that made me question if I should rotate my sketchbook at all, or if I am creating a bad habit. I know there are truly no hard and fast rules, but wanted an/some opinion(s)!

This is great and reminds me of the lessons Peter teaches in his 'Dynamic Bible'. One of the best gifts I ever have received was that book. Thanks Mom!

Do we know if he was consciously using perspective here rather than working very accurately from observation? Ok I realise that water is a moving target, so to speak, but if you look at it closely for long enough you can get an idea of how it arranges in space over time. Much of the skill then is distilling the essence of these dynamics into a representation that makes sense to the observer. Obviously, you have presented this as part of a perspective course and I don't doubt your analysis, but the purpose of perspective is to accurately represent the 3D world on a 2D surface. So I assume that it is possible that an artist sufficiently skilled in accurate observation could produce perspective views without relying on formal perspective techniques.
