Oh, thank you so much!
Oh yeah, there are these few. The second one should also include Ash, although it’s not colored and not very clear to see.There isn’t much of either of them, unfortunately, from what I’ve found. However, it doesn’t quite classify as a character sheet, but this picture, in case you haven’t seen it already, is a pretty decent front view of Ash’s outfit.
And I don’t know what form you plan on doing with Angela, but here’s one with her angel outfit, although it’s just a screencap from the anime.
