Which custom sheets should be taken down?

[GrooveMan.exe]

The Mario section has 12 Bob-omb sheets, are we going to get rid of all of those just because there's so many already like it?

If there's two or more sheets that depict the exact same thing, and one of them does it much better, then there's no reason at all we need the worse one. We don't really need sheets that lack poses, or are in a style that doesn't fit with anything (of course, extremely well-done sheets and sheets that have several others in the same style are exempt from the last clause).

For example why have:

When we already have:
