Whoa, you have one of the box tiles I ripped from a site xD.
Anyways, very good. Definitely better than other stuff people put as "maps" with their terrible use of standard tiles. If you want to make maps with standard tiles, go look at some of Zurak's work.
EDIT: Make a map pack pl0x, but oh well, going through and downloading all the maps isn't really that I wasn't used to before cs2d max.
