Request for sprites: Themed worlds!

[Iatots]

Saying "a lot of these" are ripped is kinda misleading, there is only 2 in a bunch and they are both easily replaceable with stuff that is already there.
I am a dabbler/decent spriter, I might try making a some when I decide on a theme (I think I will go catacombs with lots of skulls, have not seen a place quite like taht on adventure yet)

The big question is: what happens when cog2.0 is live? Will all walls need the new perspective as well?
