This is... absolutely amazing! I can't put it into words. first of all, the anatomy and proportions are perfect. Her hands are soo pretty and well-done! Her expresion is very lively, and just look at those folds in her dress! I especially love the top layer of her dress. It really helps define her shape. The bottom layer, though...not quite as good, but getting there. Try not to use uniform shapes and folds when drawing folds and creases in clothing. Ah, I think I'm just now realizing how well-done this piece is.

The only thing that bothers me are the cupcakes. They look quite lumpy and... not like cupcakes. They should be more .. swirly.. and less lumpy, I suppose.

Anyway, I think one of my favorite parts of this piece is the colors you used. Beautiful mix of warms and cools, and stunning color-selection here. I love it.
