*breaks critique virginity*

Looking past the bulk, her body looks to be well proportioned except for her arms. It's hard to tell but they do seem a bit short. It might be corrected with foreshortening shading it with color.

Her hair looks a bit like it's floating behind her. Try making it bulkier at the top and tapering it. It's hit her butt and bulk out a bit again before vanishing behind her belly.

I don't know how to star this... What the heck is impact.

Fourteen more words? Really? I guess, depending on how quickly she expanded, her costume would probably be completely be consumed by her boobs unless it was rapid. IE No ragged bits. Since it seems to be some spandex material.

There I did it.

You got the name right. I had to go to Wikipedia to check.

Well honestly, as this is just basically a cleaned up sketch there is not a lot of critiquing that can be done.

It looks like you pulled off the Princesses look well. She looks very much like the one from the TV show.

You did a good job making her look as though she possesses two breasts instead one. Too many artists forget the tiny details that help define a characters body.

Her hair is very vague, maybe some darker lines would have helped give it more POP in the picture. However as the belly is the main focus of the picture, the semi invisible hair seems to make sense.

If she really had expanded to that size though, I would think her belly would be more solid, lending a thought to the fact she shouldn't be able to press into her larger than average abdomen.

Overall a good job, this one could be better with a background and some colors.
