Yeah, there's also something wrong about AA between two shades for non-hard edges from a pixel art point of view, because you could have used the extra AA-colors for yet a smoother transition. Anyway, neato. Before reading your post about it being Kirby and Pokémon only I had totally thought it was a reference to all sorts of nintendo classics. I took the Magikarp as a Zora from LTTP at first (though of course it quite clearly isn't, I'm just getting stuff mixed up), and the hills with eyes for a Super Mario reference.
