The hands..
The drawing is okay (this is usual not the style I comment on).. But the hand is just so wrong, Where is the thumb? Is it another mans hand? I think you have to work on that part, and if it is the "main char's of the drawings" hand, it's in a wrong angle - or a serious bad fracture in the elbow.
I really like the texture, the skin and the lips are really great done - the hair is maybe a little sloppy, but it isn't completely bad.
- Maybe you should give it a background - maybe just another color, or a gradient :)
Sorry for the bad English, hope you understand - And I don't mean it bad, I just write my opinion of the drawing :)
