Putting aside how totally bizarre this is, youre missing a pixel on the left ear, and the left arm on its leftmost frame (left!) jitters a bit. Oh, and the right foot loses part of the outline on the rightmost frame.
If you were genuinely going for a spaghetti arms effect, the arms don't quite flow on a few frames and have some awkward shapes, and the whole thing would really benefit from some frame timing adjustments.
The leg motion looks great though, nice and smooth.
nice animation! but its really odd how the arms look when the move. It seems like they get longer when they move all the way out. Also the arms in general seem a bit too long to begin with
His left hand going behind his body is kind of funny, because it shows up between his legs, and just enough so that it looks like it might be his genitals. That fact that he's wearing shorts kind of helps with this illusion.
Because of his legs are always on the ground, animation makes a bit of moonwalk-ish effect.
Thanks for great feedback! I will be careful next time!
