The palette you have is a bit contrasting in style. It's trying to be too much Rondo and SCV4 at the same time, notably the skin versus the gold trim. Examples attached.
I'm retooling the palette to be in the same general style as metroidquest chose to use; more like Rondo. I found that the Adventure Rebirth whips actually accompany the sprites quite well too. I'd recommend using them, fit to the sizes needed. Speaking of which, metroidquest, can you please post the sheets of all the whips you currently have in use? I can format the Adventure Rebirth ones to match the size required.
In addition, I'm removing the added frame in your whip animation, X. It's only an arm change and looks odd because of that. With the Adventure Rebirth whips it also not necessary. I have also added a frame at the end to go along with Adventure Rebirth's last whip frame (where it returns). It doesn't have to be used but I think it adds a little flow to it all. Attached is an animated example of all of this.
If you like where this is going, I'll continue to go ahead with this and post a full sheet when done.
