Custom Ceroba Samus sprite

This project is mostly to see if anyone can give tips. help, etc to make a fully functional custom resprite of samus as Ceroba from the fan game Undertale yellow. I do not own Undertale yellow or Ceroba, this is purely a non-profit fan project to bring Ceroba to super metroid since she is my favorite Undertale yellow character and her sprites just need a little tweaking to fit in super metroid.

Just a few issues of what I would use as her jump sprite since she doesn't have any good jumping sprites, and I'm not confident in my pixel art skills to make a custom one outside of mashing 2 together. I have made kinda made some custom sprites by combining 2 of them, but I'm not sure if I can do that for all of them, especially the jump/wall jump sprites and other sprites that I might not be thinking of right now might be an issue later.

Basically I'm asking for any tips or help with sprites, especially jump sprites of her would be appreciated

To play as ceroba in super metroid, you have to use the sprite something program and inject this PNG into the game file whether be vanilla or a rando seed. 

This project is solely a fan project and just to be used to replace samus's sprite in super metroid
