To me your drawing feels a bit long and thin. Especially in the upper torso. Also the arm feels a bit long, even though I didn't check your drawing by measuring the proportions. Additionally I would lengthen the back of the head a bit and lower the ear. Other than that great job on the lay in. - Philipp

I think this is great! Very clean and easy to understand, i think i have a few things to point out though, i think your rear delts ends too early, i would make the muscle belly thicker, and i noticed the teres major that you drew inserts all the way too near to the spine as if it is the same origin as the trapezius.. but it's what i think i'm not 100% sure.. Hope it helps! Keep up the great work!
