I thought I had more than these, but I can't find them if I do. If they turn up, I'll pass them on as well. For now, it's just the Littleroot trees and buildings. The odd Pokécentre is by Newtiteuf. Link
Yes, I did. It seems you didn't get my reply, though.
As I'm here, I'll reply. You're perfectly able to use the tiles from LE, but they're simply a few rips of houses from Kyle's new Hoenn set. It's not really a tileset in itself, but if you're just looking to add to an existing one, I'll send it over
