Needs a little more matching. The blue-white in the winglets don't match anything, for sure. The purple could be added in a bit more. I'm not too much a fan of the musketeer pants, which I bleieve those are.
A pair of gloves or something for your hands is needed. They're very plain right now. x: Especially in a default position.
The skin showing on your waist in splotches doesn't work too well either.
Add some more white to help the buckteeth mix.
The hat..I don't know. I don't really like it, personally. Maybe in a few outfits, but not many at all.
Geez, this is long, I'll quit now. x:
