I did some study tonight on muscle anatomy in the upper and lower arm, because I started doing a commission and realised I desperately needed to get better at drawing arms! Thought I'd let you guys see what I'm up to if you're curious.
I've recently been watching and rewatching Proko videos on youtube, and he has an anatomy series. Muscles, bones, tendons. Good info in a fun package, if you're familiar with drawing and looking to improve.
