Yeah, good point; I dig your edit. I originally just doodled the rock formations in bright blues, did Proto in isolation, and then did the rest of the scenery. Should've gone back and changed those colors after I settled on the final colors for the rocks, but I was too focused on everything else.

Solid work! The animation is simple but effective.

I think if you make the shadows on the character a bit more purple, and the oranges on them a little warmer, they'll feel more like they're in the environment, lit by the sun. Here's an edit trying to adjust the colours to that effect.
