The hair and helmet/mask is what kills it for me, personally. If she kept the domino Ms. Marvel mask and hair style, or even just the hair style, she'd look pretty awesome.
The attire itself, a visual homage to Mar-Vell, is cool, though.
The premise is also a good one as Carol's basically just been in the background of Bendis' Avengers. And Marvel does need a strong heroine solo title.
