It looks rather awkward to have the characters and ground pressing up against the canvas edge. If you give them some breathing room, or make the background transparent to hide the edge, that would solve the problem.
It also seems that something went wrong during making or saving the image, you have 500+ colours, most of which are redundant variants of other colours that occur only for a few pixels each.
