Thi is stolen from the MineCraft map. All he's done is take parts of it out.
TNT doesn't look like that, you should change it. Same with the creeper, squid, player, and zombie. Not that it's bad, but it would be good if you actually copied the pixel maps for the tiles and mobs. @Lacrosse: Yes, there are fish, but as of now they are not a mob, only an item.
