This would be my second experimentation with sprite editing, and I think this is a job well done. As you can see, these Pokemon have aspects typical to what you would see in ghost typings- eyes that simply look like death, a shadowy aura, and particles. I’ve always loved the color scheme of a normal, shiny Slugma, therefore that’s what was used as the base.
Very Spoopy, if you’re trying to keep the body types similar to the originals then it looks perfect. (as in dead slugma’s) if you were trying for a variation on the pokemon, i’d probably have the bodys look more spirit-y or like rags in the wind. Both are perfectly fine options as deltas, I just kinda wanted to know where you’re coming from. (also slugma seems to be putting on the pounds XD)
