It's kind of bothering me that the head seems to have less frames than the body, because it sort of makes it out of sync in that the body is moving more than the head, plus it just makes the head seem detached from the body. It could also use some transition frames to smooth out the animation. Unless all of that is part of the parody? I have never seen the original sprite animation so I do not know if it is for the sake of humour, in which case it's fine.

Either way the sprite itself is rather well done, I am not spotting any sorts of shading errors and despite the low frame count you at least seem to know the general movement extremes when animating.

Wahahaha, okay, I just saw it. It does look pretty silly in the video. The only reason the animation lacked smoothness to me is because it seems to be playing a lot quicker in the video, so this is pretty easy to overlook since GIFs seem to play more slowly in a browser.

It depends on your browser.
