That definitely looks 2D, Ry! I forgot to try freestyle on him, not sure if it'll look better, though, because it'll break the seamless colour of the shade with the background. Toon shading is pretty simple, but that's the problem, you don't know what to do with a simple setup XD

And since it's not organic (he's a robot), the weight painting for animation is simpler than an organic character. But I don't know if I want to try animation soon...
