Don't know if this will help but not a good 2d artist so make it up with my 3D skills. I have a basic ghost model which I sculpt or resize according to my need for each ghost. After that I animate different poses like idle, sex and knockdown. After that I export those images to I can work with them in Krita. There it's just like refining a rough drawing. You still need to work on hairs, cloths and other things. This is what I do for humanoid characters at least. Objects sprites are a lot simpler than this.
