Going through it now, fixing the errors, I'll reupload it when it runs again.
so far the only errors you have have been entity's out in the void *lights* and walls not touching so it would cause a leak.
The way to find a leak is. File>run map. When run map is complete go to Map>Load Pointfile.
You now have a red line on your screen/map. Follow it fix the problem.
So far biggest problem is you have snap grid off, which is a big no,no. to turn it bad on click SHIFT+W.
EDIT:
Sorry bud, spent the last 30 mins fixing leaks.. there is only 3 ways of fixing all the leaks *i did up to 11*
1. Rebuild the map with snap-to-grid
2. build a big skybox around it, *will make the map run, but bad style and drops fps and such
3. fix the leaks. would take you a long while.

I personally wouldn't release this. As a first map i think you went over your head as far as you skipped the basic brushwork and went to break walls and triggers heh =)
First maps generally as a rule are never released, hell could even hurt. The last thing you want for people to remember when you release a second/third map is people to remember how your first one looked.. and hence overlook your newest =(
We had a thread here a bit ago, avg mapper does about 5+ maps before ever releasing one. Not because anyone is perfect, but there is SO much to learn in hammer it takes about that in time lol. Heck i can't tell you the amount of hours i have logged in hammer and GTKRadient and still learn something each time i open them up.
As a first map you did well, a bit much, but very well. Providing you take my critique the right way i can't wait for the second or third map!!
