you know, you're tiles are looking really raw to me... that's the fault who is almost everyone doing who ripps dpp tiles... it looks like you ripped it from a screenshot and after that you did nothing more with it. imo it would look really terrible if you insert it and the other tiles doesn't look, for exmp. like yours, like originally dpp tiles. you should fix it up a bit til it looks a bit like gba graphic... i'm sorry for my bad english, i'm from germany...
