(i wanted to upload this video in response to this anon’s message so pretend that this is an answered ask post :D)
Don’t give up! Your studies are of use, you’ll get there don’t worry.
Please read this ask that I’ve gotten before, I feel like it’s important for you to know that everybody goes and went through the same thing.
I wanted to upload a video to show how I draw studies because I think it is important that you know how to draw ‘effectively’. When you are practicing anatomy, you shouldn’t treat each drawing like a final drawing (so that you spend a long time in one part of the drawing or drawing very clean like it could be line art).
How I do it is that I hold the pencil very lightly, I’m barely putting pressure on the paper and I’m letting my hand move across the paper. It’s okay to mess up while you practice, just draw over it again and don’t bother reaching for the eraser. The whole point of studying anatomy is to have that flow, to know where to draw the lines, and to be quick, and you can achieve that by practicing.
