I think the most brilliant part of this animation, is the feeling you gave it. Even though the music isn't what you'd expect from an RHG Battle, it gives the animation a really good vibe. Nice work David!
Well he's actually an escaped computer program designed to collect information. When he "eats" his opponents, he's trying to learn something about his opponents. I wouldn't use the word "eats", just because Mr. Pix doesn't need food. "Absorbs" is a slightly better word.
It's also very likely that I'll be exploring this habit a little closer in the coming series of RHG tournament animations ;D <3
