She is more angsty than she has been in the past and she has less to be angsy about too, which is the point. I'm just not a fan of her New 52 self, or the book she is in, but that's just me. At least they put her in better costume instead of basically underwear though. I'll say that is at least one plus.
Also the Hawkeye Initiative strikes again:
What is the point of posting that picture? Men has never worn something like that even as a bathing suit, but starfire's outfit does mirror a female bathing suit. Putting up that photo is as ridiculous as putting up a photo of men wearing a bikini and call the society sexist because they are encouraging women to wear skimpy bathing suits.
She also wasn't that modest pre new 52.
