My husband and I made a map a little while ago, its called Celestial Seals. There are several lets plays we need to post up on our channel What I really need is a trailer, as our original person who did a trailer/review deleted their youtube and has not been on the forums since June. You can do a lets play too if you want, its an Adventure/Parkour/Puzzle map that's very wide open. Ignore the 1.2.5 patch note, because the map it perfectly playable in 1.4.2. Here's a link to the forum post so you can check out some screenshots and posts. Also, if you decide to make anything, please either pm me or bump the OP by posting!!
Sorry I never got back to you but after testing your map first I wasn't really enjoying it because of the fact you have nothing keeping it night so that you have to switch it over every time you want to keep playing.
Maybe set up a clock connected to a command block with /time set commands or figure out how to lock time.
