About snappy- and robotic-lookingness, I actually kind of aimed for that. I wanted him to do a really energetic run, and I quite like the 'snappy' part.
But robotic? :( Not really what I aimed for. Well, thank you for the critique, I'll see the run in-game (I wonder when) and I'll of course consider your critique. Right now, though, I'll leave it, as I have to get on with other stuff.
(note that your edit seems to look better and less snappy at 2x, while the eye fills in a lot of the snappy gaps in mine at 1x, at least that's how I see it. In that case, mine would be favorable on a DS screen. But now I'm perhaps just rambling :>)
