Here are my assignments, with these, I tried to understand how muscles twist. I appreciate the criticism.

Here are some of my quick-sketches. Hope to get some critiques.

Another Batch of shading studies, could someone give me honest feedback of these? I'm having trouble with the bounce light also having trouble with placing the cast shadows to look somewhat accurate to the reference, Honest feedback needed please thank you.

I drew vertical line with the ruler, divided it (7.5 heads) and followed Stan's instructions. Was not hurrying and tried to find right position of arms, hands, legs, feet and other features in relation to the figure height and width and overall figure shape and then added a bit of lines describing shadows. I have corrected position of left model hand and the right model arm, both positioned ca0.5cm too high. The final result as on the attached pictures. Just wanted to exercise and see where I am as for today.. (WHS sketchbook, A4 size, HB mechanical pencil).

Here are my assignments!!

Hello!!! Finally we got to the hands. Here are my assingments

Hello everyone!! I made this drawing to better understand the bones of the arm.

MORE ARMS!!! I had problems with some arms. I appreciate the criticism.

finally at the arms!!!! Here are my assingments.

Yes it was hard for me, I think every artist struggles with that. What helped me was having 2 sketchbooks, one for dirty and bad drawings where I don't care if it turns out good or bad. and the other for more finished drawings (not perfect). I think something that can help you is to use a pen, so you can't erase and slowly stop having that perfectionist urge. Be messy! (I will give you some images of my sketchbooks). These episodes of the Draftmen podcast helped me a lot (check the last link first if you want): 1.- Draftem S3E09: Sketchbooks.

One of the best comic artists in the world, Alex Ross, uses photographic references (Ask Alex Ross: Why Use Photo References? https://www.youtube.com/watch?v=0InB6axv024, How Alex Ross Creates Models for his Photorealistic Style https://www.youtube.com/watch?v=TBxPsVUge9s&t=158s,) So don't think that the day will come when you don't have to use references, nobody has a photographic memory. Now, if you want to stop relying on reference alone, that comes with a lot of practice and observation. References will help you expand your visual library, and the Drawing Basics will help you put your ideas on paper.   By the way, it's not bad to copy, if you copy the right things. It is good to copy aspects and qualities of your favorite artists, that will help you improve your art.
