firstly, heres how the sprite works:

which is whats currently being used in the game. I've never felt happy using it, and Ive improved it a little every so often from the original which was so damn subtle it could've been used as an idle anim.
heres what I made just now:

as you can see its pretty awkward, the main cause is because the sprite style in this game is flat shaded with some inconsistent outline rules that I haven't got around to finalizing.
that said, I don't want to add any more frames, nor do I think I would need to, and they have to work under the structure shown in the sheet which can be a blessing and a curse...
k so anyways, I really need some advice, crits, edits, whatever you have.
Ive remade this jump anim so many times I just cant think of a good way
edit-

made it go up and down for a better idea of what its like in motion, I didnt do it that well tho lol
