Looks like you used just 2 textures, well I can't see the full view of the level,but It looks pretty good.
This world is 10% finish. And i search more "Super Mario Bros." Textures from: Nes, Snes & GBC.
I will not use the Textures from newer Mario Bros. games. I have changed the Block Textures for
10 Minutes ago. I have now: 5 Perfect Textures from ??25?? I hope i [am] find more nice Retro Textures.
