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.

Alright, I really love this picture, the character is very adorable and stands out nicely against the background. Overall, the colors are very well done, and there is not one thing in this image that is too "overpowering".

One of the things that I would like to say, is that (this is mostly my opinion) that maybe that each cupcake should be a different color. There's a lot of purple in her outfit, but her hair is blue, and I'm also noticing some green.

One of the things that I really like about this picture, is how it seems like she's greeting you as if you had just walked into a cafe, and it gives the image a really good flow.

This is a really amazing image, and it has managed to make me hungry, so it just proves to me even more that it's an amazing image. Keep up the really awesome work in the future!
