also graphics gale is too close to paint to be outside of anyone's comfort zone! Like you know you choose colors and then you paint with them! But you color select with the right click. And you bring out the marquee/move tool by right-clicking! And that's all you need to actually pixel! ' 3 ';, I don't see what's uncomfortable about it except for .. how it might look or something
It's troublesome if you're used to right click being a second/background color ):
Is there a reason the timing on all the frames is 10cs? Can you not use different numbers?
A timing edit (no edits to the sprites or placement, just changed timings around):

I tried to make the motion have more snap to it, but that caused me to speed it up too, whoops. Anyway, attempted to build anticipation by having short pauses before movements, and then keeping the frames where he's moving between poses rapid (like when he's in the air, before quickly turning into the kick)
I would add a few frames to smooth the movement out, another after the first kick (frame 4) that he would pause one (so frame 4 could be sped up), and one when he's coming down (after 16) so the transition to landing is less abrupt. You should also either change his placement or add a frame before the jump, since he turns in place instantly and the feet swap positions O:
