The pose truly is kickawesome. The cloth from the weapon flying around really adds to this, it's seriously an awesome picture. There might be many colors around, but I think they fit together in their own odd (and cool) way. The handles on the weapon make me think of a certain type of boomerang, like the ones Aika from Skies of Arcadia uses (yes I know the anchor looks different now, but still).
And a personal opinion, I'm happy you didn't integrate the stars in the outfit she has nowadays (or her battle armor), because I think that they don't fit the character and are looking slightly ridiculous (the one on the bra is okay though, it's mainly the tights).
