I'm not really a fan of the art design yet, for two main reasons:
1. I doubt I'll be able to take the enemies seriously if they're chibi.
2. It honestly looks like someone took Black and White and tried to force it into being 3D. Nothing looks natural to me, all of the rock structures and trees and stuff look like they're from templates, and the grass looks strangely flat.
I'm sure it will grow on me eventually, but the art style just really bugs me right now.
