I think it looks very cool. But I can't design fortresses worth beans.

If anyone feels inclined to give mine (http://www.bay12forums.com/smf/index.php?topic=128101.0) a whirl I really could use some constructive criticism. I intend to make as full and clean a graphic set as I can. I'd love to have anyones help that is willing to give it. The tileset can be used without the graphics set. The only downfall is that it requires the true-black color in the color scheme. Sorry for tooting my own horn. End of my shameless plug.
Now that I am done tooting my own horn. I am a big fan of this tileset for higher resolution machines.
