hi wanserdang! welcome to the competition. =]
#81 is a cute design. but i need it to be a bit more edgy and dangerous. i'm not sure if the butterfly is congruent w/ the demographic. but that doesn't mean it's a bad idea. if you think of a different way to interpret it, then it may still work.
#82 and
#83 is a great feel. it kind of reminds me of the tv series, DARK ANGEL. i'm not sure what the wings are made of, but perhaps you can tell me what you were thinking when you designed this. it's a little ambiguous. also, be careful with the platform heels. culturally, it may be interpreted as strippers.
if you want to have the flyaways on the wings, take it out more. perhaps turn them into swirls and exaggerate them a lot more throughout the entire design.
lastly, what is on her shoulders? i thought it was a sword.
