Nice to hear that you plan to expand it to a full level!
Everytime I check out levels from box maps contests, I happen to think "this would make a great middle ground for a CTF map" or "this would be a good atrium for a deathmatch map" :)
The map was made for the levelsource.com mapping competition to fit a level inside 1024x1024x1024 dimensions, so based on that, it is easier to swallow its size. One day I really need to expand it and make it a full level.
