Very nice work here! XD

This looks lovely. You've handled the character's quite busy design very well - It doesn't look busy at all in your drawing, even though the outfit largely has the same elements.

I like the colours too, but it's a shame her body kinda fades into the background. On a pic like this, especially with such a close-up light source, you can easily add some darker lines, or brighter rim lights, here and there on the edges of her figure.
Oh and don't forget the drop shadows! Like under her arms there. Shadows can really help to ground a character in the surroundings so it looks like a background rather than a backdrop, even when the background is very simple like here.
