A drawing I did of yamato from one piece this year!

Something im hoping to learn is if there's a "correct" way to measure the actual length of foreshortened objects. Often when I use foreshortening, extreme or not.. I mostly go by feel! Is there some sort of science to it? Can I really know if the exaggerated, foreshortened arm I draw has the correct length.. it bothers me I dont have a reliable system to check if it's correct. What happens when I combine it with convergence and overlap on top! so many things to consider.. Anyway! Here's a bunch of drawings I collected that I love. All of them have some sort of combination of DCFOA in varying degrees. 1. eo58 - 4, 5, 4, 5, 3... Objects definitely appear a lot smaller in distance, seems like 2 point.. cant tell if they go to a 3 point above without going in a measuring, but it is a low view looking up so it definitely has the "nature" of a three point perspective since we usually look more extremely up or down at something when a third point is introduced. The foreshortening I would say is pretty extreme, look at the cars in the background, can barely see them, and I would say the human is also pretty foreshortened.Definitely a lot of overlaps here, almost every object in the image overlap something so high rating here makes sense .. atmosphere is definitely fading in the distance pretty clearly, dont know what rating to give it since I dont look a lot at pieces with atmospheric perspective... SIDE NOTE: I am so interested in learning how you even draw animals and humans with a lot of foreshortening and perspective.. and make it all make sense! Right now I have no idea how I would even approach a piece like this and being able to fit everything into a 3D space 2. Stephen Gian - 3, 3, 5, 4, 2..objects gets smaller, at least if you look at the body as simple forms, right foot is very close to us in the top left drawing, but his left foot appears smaller in the distance... there is also convergence at play, look at how the letters all converge and they're all sitting on a plane that could be simplified as some sort of rectangle. In the bottom drawing there is a wall too... it SEEMS to be following perspective, tho his body makes it hard to plot out the lines, but it is convincingly "3D". The foreshortening on the arm here is also pretty extreme, and overlap is being used in combination (the fist covering the forearm, which also covers the upper-arm). So overlaps are actively used here, other examples: look at how top right drawing is drawn: The head is in front of torso. the upper leg covering the bottom leg, covering the feet! Some atmospheric perspective too in the background. 3. Dino - 2, 5, 3, 4, 3.... atmospheric perspective, look at how the objects that are not in the light become darker. Convergence is also at play, look at the floor and the how different objects have different vanishing points. I believe it's two point perspective, but some objects in the rooms also dont follow the "traditional points".. look at the tilted canvas she is painting on, or the object she is sitting on.. not to mention all the paper laying around going in all sorts of directions.Also it's interior, I have no idea how that works, but I think she is sitting inside of a 2 point box I guess? haha. 4. DUMOG - 5, 5, 3, 5, 3... great use of overlaps, great use of perspective.. feels like im being "drawn" into the piece 5. Dino - 5, 3, 3, 4, 5.. I like this piece Sorry for not writing much about these last ones! I got tired. Great video as always Marshall!
