No offense, but inverting colors on an existing sprite is not called spriting. Here, we call it copying.
Yeah, i am not a good spriter myself but maybe you should start
off by making something small from SCRATCH.
I don`t care if t is made up of two dang pixels make somethin oringial.
Hey, a lot of people make damn good edits. They don’t need to be scratch. But this isn’t even a proper recolor, much less an edit.
