its neat but i think you need to fix the jumpiness of some of the body features before worrying about polish. thb this is the most detailed you should be at this stage while working on the motion. note that this is a pretty huge pixel animation and you shouldnt expect to finish this one overnight.
having said that, i think there are some real perspective inconsistencies happening with the zebra body. If you consider the face and forelegs as one part of a zebra, and then the belly/back and hindlegs as one part of a different zebra, you can see how the front of zebra A looks like its running towards you, but the middle/back of zebraB looks like its running from left to right, more of a side on perspective.
Im not sure thats going to be a 'fun' thing to fix, as i suspect that would call for a decent revision of the entire animation, but in the end if you could make the back and hind legs match the perspective it will be a much stronger piece, even at this scribble in stage.
