I really like the design of this. The look is very feminine and she looks very fit and slick, which I find fitting for a champion of sky, she looks like she could breeze through the air and other terrains quickly.
I like how you have manage to make it all really compact, only minus maybe being that from the front her backside shells make it look a bit hollow, but it doesn't bother me that much.
At first the split coloring looked a bit cheap to me, but after giving it another look, I think it makes her coloring look a bit more "complex" in a way. I think it would look a bit dull with full white or dark silver. Speaking of colors, I really like how her blue weapons add to the characters colors. The arms and the top part of the mask could look a bit out of place if her weapons weren't blue. Plus I find that the clear blue gives her a bit of a "cold feel" to her look, like she's quick as the cold wind.
Any possibility for instructions in the future for this?
