Regarding the card frame, I can remove the internal illustration, leaving only the border/frame; the file is already ready for download.
At the moment, it’s not possible to further separate the frame into layers, as the original file isn’t layered, and reconstructing the card from scratch would be too much work.
As for cropping the illustrations (so just the illustration without the card), that’s doable, and I’ll let you know as soon as it’s ready.
If this is what you meant, I can go ahead and proceed :)
