Sunny castform is the one I care least about, so no surprises that I've never drawn it before.
I just wanted to complete a set (of four in the same style).

I had no idea how to pose castform so I figured I'd do it using weather ball, and then had to look up how the move weather ball looks and tried to imitate how it looks in the anime I guess but at some point I just placed the ""flames"" entirely based on vibes. God those don't even look like flames.
