Awesome! The tiles give a very colorful and bright feeling to the game, and they're beautiful! Just one thing, though. You should make the outline for your tree's upper area a bit brighter, because it looks very odd.
Your Pokémon Center and Mart tiles (inside and out) are great, too. I really like the light shining out of them.
I can't wait to see the new Pokémon designs, and I guess to play this game.
