work on your drawing skills
I liked how you went in the direction of animating the wings. Though the shape tween (when the wings rise) doesn't work too well, it's good to see some movement.
Clothes are fairly generic. I liked the jester's cap and some hairstyles were cool, but all the clothes with only nominal differences or colour swaps seemed dull and pointless. Give us some crazy fun stuff!
The basic character model was kinda sloppily drawn, with overly long torso and short legs. Having a mask as a face seems pointless - if you're gonna seperate out the face, have different expressions etc.
Ultimately, dress-ups tend to be dull and as a result, if you want one to stand out it needs to be really polished. Yours has some good elements but you need to work on your drawing skills before they can stand on their own, without gameplay or a joke/narrative to support them.
