you look kind of cross eyed and maybe the smile shouldnt be such a curve......
and the wings are kind of too detailed for the rest of the picture i think...
You're right on the mouth. I'll fix it in a little bit.
Regarding the eyes, I was trying to make her reading the book, but it didn't turn out very well.
sweatdrop And the wings are mostly habit, although I
could make the wings more simplified (it'd involve redrawing the sketch, though, since I don't trust myself to do it right on the computer freehand with a mouse).
