Not bad.
~ Animation/Graphics ~
All I can really say about this submission is that the great animation and graphics really boosted it's score and rating. It's really the only great thing about the submission. You can draw pretty good and the animation was smooth.
I wouldn't have mind seeing it do a couple of different things though. It took the same amount of steps, stopped, looked up, etc.. The same every time as it looped. I think perhaps having it walk a different distance, move differently, etc.. every time would make it a bit more interesting. Perhaps about three variants so by the time it repeats again it's not so boring seeing the same thing over and over.
~ Story/Content ~
Hm, I guess it was sort of relaxing. Perhaps it's not something I enjoy relaxing to. :P Perhaps you could have drawn out about 5 or so different backgrounds and gave people the choice of which background they wanted to choose.
Perhaps a dirty sewer, the park at night time, inside of a house, etc.. Some basic things like that. I think you could do a pretty good job since it looks like you can draw pretty good.
~ Audio ~
Not a bad song at all. Not really any room for improvements here since there wouldn't be any reason for a voice or sound effects.
~ Overall ~
Not bad. I wouldn't mind seeing the choice of other options as backgrounds.
