She's pretty sezzy. =D Actually, the lips look ok. I love the eyes. Personally, I think adding some shading and more detail would add demension to this piece. I'd like to see it in colour. =) Good work.

I think her lips would be okay if you straightened out her lower one and put the upper more center... o,o... her eyes are really cool, the left seems a bit larger then the right though. nice job so far..
