Well, both of these rather meh to me, but others' mileage may vary. Apparently the new Superboy is more Hank Henshaw than he appeared to be in Teen Titans, unless there are actually more than one of them around in the DCNu.
What's happening here? Power Girl has a similar costume. The boots are interesting but I'm not sure I like them. Too much sex appeal there which I don't think fits Supergirl unless DC is aging her. Can't make heads or tails of the Superboy art. Too much Japanese anime style art going on in both pics.
