I don't know much about Super Paper Mario, but this is a pretty unique tileset.
Looks like a house of some kind. Has the right block priority.
Some arrows and floating platforms.
I noticed you have other tilesets stored in the level. I'm not sure if that's intended.
Personally, I'd love to see more screenshots as a guide to determine which tileset is which.
(Though, I'm new to ExGFX, so take my advice with a grain of salt.)
Other than that, good on you my guy.
