For the illustration I was doing earlier, i took something from two different things, like the hair and some cloth details from one, and the anatomy-pose of the other.
I can draw faces, eyes, stuff, but I'm terrible at arms-hands-shoulder, and most of the times I have no idea what pose to do (for a comic it's easier, but if is a single illustration, i need references, because I'm blank at what to do with the arms-hands).
