Just gonna echo that Wonder Woman's looks the most off of them. The pants just really don't match her outfit at all, and that alone just messed up the look. A few other things look off but can't quite say why. Yeah, "cosplay gone lazy" fits that description.
Power Girl is another case that feels off, I guess feels like they put too much on her that wasn't necessary. Like if they just took her standard outfit, put the blue undershirt thing she has in that image to cover her iconic hole, and put on pants, that'd be enough, but they went the extra length and...eh, dunno, feels off, can't say why.
Most of the others are fine though.
