Big improvement from the original. I didn't comment on the anatomy in the thread, since you specified that you were practicing on colours and shade. The colours and shading looks good, but the head looks strange.
His ear is too high. Normally, the top of the ear is roughly the same level as your eyes.
Right now, the nose and mouth seems to suggest a side view, but the general shape of the head and the eye looks like we're seeing it from a front-side view.
It's very Picasso :)
Thanks for the kind words!
Frost Butt, thank you for helping me. This would have looked a lot worse without it.
CELS, I'm not going to work on this anymore, but i'll remember what you wrote and try not to make the same mistakes again.
