Lookin' good, Erick. The building looks like it was inserted very good, so keep it up! By the way, maybe you should make the building a bit brighter, 'cause it's Kyledove style, and you know how that is... And the palette of the grass looks weird, maybe somethine less... well, I don't know how to put it. :P
By the way, you should use a different variety of grass tiles instead of just the brighter grass tile, because it looks plain in a Fire Red ROM. Well, keep it up, amigo! I hope to see more updates, man!
