It's hard to add to the excellent points Wolf and Moon and already made, but one thing sticks out in my mind here.
I've devised a map with 15 points of interest (label with x's and the corresponding number). Certain x's need to be completed to be able to enter the next part of the dungeon.
If you mention a map in your sub, then include the map for the readers. Nothing is more useless than a reference to a non existing part of the sub, it makes the idea of zero value to the reader and will only serve to frustrate them when they look in vain for the non existent map.

I concur whole heartedly with Moonhunter to put this back in your working folder and give it a complete overhaul, it has potential, but not in its current rough draft format.
