Well everyone commented on the hand so I can't nitpick about that much >> damn. ..Actually I will anyway.
Aside from that long index finger, what's going on with her little one? For the size of her hand it's tiny, even for a little finger. It needs some more fat on it and length.
Also the cuff on that arm should puff out more from her arm, it's too close and is thinning her arm out in an odd way, especially how the cuff folds go in then out again, it's gone into her arm! Just a little but it's there.
The hidden side of her face, the cheek's maybe a little too far out, especially as her head is turned and you should be seeing less of that side than the other.
Something bothers me about the closer leg but I'm not sure what, it just seems kinda flat to me and I can't think of a way to change it. I know what bothers me about the other one though. Her thigh where it comes up to the knee disappears, she's lost a bit too much fat there as it comes to the back of the knee, a bit of a lap over where the calf and thigh meet wouldn't hurt with the angle her leg is at either.
Ok, aside from those I don't think there's really anything else I can nitpick. Well ok, the fact it doesn't really give the feel of lust to me, but eh. She's gorgeous anyway and I like what she's wearing and the way she's sitting, it's all just lovely. And damn you for being able to draw such gorgeous faces and hair. They're just lovely.
Anyways, hope I wasn't too nitpicky but you don't seem to mind too much.
Lovely drawing and keep up the good work! Enjoy what you do and keep doing it!
Happy hunting!
