It's an alright loop, not much of a reason for it to be hear instead of the art portal(though I suppose the background wouldn't compress well as a gif)
But for running this looks a little goofy, stiff and slow. I didn't know he was running until I read the description; I thought this was to make fun of old Adult Swim show animation that were forced to re-use old 80s cells that ran at 12fps. I think you may have spent more time rigging, the background parallax and making sure the shadows and highlights looked nice each frame rather than focusing on primary(a panic run where the torso bobs forward and back) and secondary motion(head bob) to the loop.
