Yeah, had to cut the background for each, mostly Mulan. (That’s actually why I kept her background in the bottom right, I’d gone ahead and blended her into that one as well, but then decided to keep at least one original background for her.)
I actually didn’t recolor most of it, which is why that bottom left is so jarring (I still need to redo that one day), but what I did, I did for each layer at a time, and used clipping masks so they wouldn’t apply to the rest of the frame.
