One thing in particular that's throwing me is the position of the eyes. The nose is much closer to one eye than the other.
Yeah, there's a small story behind that. I had to have this done for a class in time, and I was doing it the night before. The eye was originally farther from the nose, but in my reference picture, his eyes seemed closer together than I had them. So, rather than attempting to redraw his face (again), I just shifted the one eye over slightly. Cheap, I know, but this is only for practice purposes and I was sorta running out of time.
Forehead kind of scares me (don't do the axe arm thing again)
Why does it scare you?
