Good, Improve as you work.

Grrrr

I give you very much grudging respect for this, as hands are the bane of my existence in art. It's well drawn, and everything is in the right place, but it seems as though it can't make up it's mind whether to be realistic or cartoony. I'm not sure which you were going for, but the lines on the palms, which stand out a bit more than they should i think, make it look more cartoony. Excellent work still though. =]

Nice

I find its perfect , the shading , details and the perception. continue like that!
Now try with a body . :P
