These are pretty good, i like the varying use of colours on each portrait. Something bugs me about Kat's face though, i think it's how bright the blue comes off, seems a bit garish. Good work non the less though.
"Wegra" if you're going to give someone a review then don't give them a shit score just because you don't like the game, you're meant to be reviewing the art... a useless and abusive review.
