I also really like (#48)Anahita's 3D model, I thought trying to get her water hair in 3D would be tough but its seems they managed to pull it off.
Yeah, man. Just browsed through all the most recent videos, and before I posted a few minutes ago I'd have said just the designs of the last few are all good but seeing what Atlus has done in the animations too? Good stuff. Graphically this game is looking like the true successor to Nocturne.
Wrt to the demon designs themselves, I'm also impressed at the spread Atlus has achieved. Look at just 46 through 49 and the range of designs varies from grotesque horror to cute with some stylings of low-key horror to wlid and magnificent to simple and clean with a still very distinct flavor. The only one I'm not sold on is #45 which looks a
little too much like an edgy pokemon, but they can't all be home runs, right?
