I was looking back through the art, I really think the time of how long its taking them to churn it out is a huge plus in G's favor.
I'm not really liking the stuff from K, though the monster does look nice - the rest I'm not too fond of. Maybe with a background it would be better though.
I actually love studio H's mockup, I know the concept art isn't how it'll end up looking, but I actually really like the concept art background. Its not in theme with AVWW really, and I'm probably a minority, but I like that surreal/sketchy look. I am sure the pixelated version they come up with will look rather different, so that's not really an endorsement of the final version.
