I really like this piece. The only thing that seems off to me is the angle at which the axe head is at. It should be nearly parallel to the back of his hand, and it's at about a 45° angle. Other than that, it's quite nice.
Hm, yeah, I think I see what you're saying. I think It's an unsuccessful crop on my part, showing only part of the curve of the axe, giving an impression of a weird angle. Thank you for pointing it out, I'll see what I can do to correct it
