Here is a map I just finished. It's great for 3 on 5 comp stomps, and decently detailed.

I'm very pleased with this map. It is exactly what my friends and I have needed to make multiplayer games against the computer decently challenging. Check it out. You can download it here, but I would like for it to be hosted on your site if you feel it is good enough. Let me know what you think.
