Like the trees and the flowers a lot. Not a fan of the clouds, though: they're so square, and practically featureless on the inside, that it feels like I'm looking at concrete blocks. Not very whimsical. :|
You can climb beanstalks (not pictured) and walk on the clouds, so they still needed to be functionally shaped. They could be both, I suppose, but I'm intentionally avoiding angles to make it feel more game-y, free up more dev time/tile sheet space, and distance the art from Earthbound's a bit more. I am thinking about adding little things to give them a bit more features, though.
