Well it look like you guys have been more ambitious than me! I've just been doing an Arena map, which (if I have time) can be converted to a KotH map too. I have pretty much got the playable area (the stadium) done, and am now just working on outside and the skybox. I have added a few more lights, and changed the wood textures so hopefully the purple checkerboards are gone.
(Not pictured: a Mesoamerican carving of the Heavy's face; well, there's more than one)
EDIT: Thanks for the heads-up Vincent. First time using Dropbox.
