So I made this and thought I'd share it with you all. I'm surprised I could compact it as much as I have. On cubehamster's server, I have 2 designs, they're massive compared to this one. Anyway, this is my first upload, and first map.
I'd appreciate some feedback as I'm new to map-making.

EDIT - As I didn't have anyone to help me test it, I had to do this in singleplayer. A few days ago, I tested it with a friend, and some of the command block stuff didn't work. It would've been nice if one of you could have told me about this. I'll work on fixing this.
