I like everything about her except that dumb skirt ugh
I don't see anything wrong with the design. In fact, I think is one of the best along with the one from Suetsugu (that one look that if was designed for a Pokémon game though).
Also, the one from Toru Nakayama is not bad at all. I can see that character as an NPC in the game.
It's cute that they want to involve the players, but I feel there are other ways to do that.
For a Mega Man game, this is the best way to involve fans into the project. Fan feedback can work if is not too forced into the development of the game, and after all this years we don't want a bad game because of bad decisions made by "fans".
