every hallway is the same, and while a good and unique layout that flows is a plus-side in a map you need to fill it with appropriate details and have it fit the strategy of the game modes. i'd start again from scratch or choose a different theme for a map, i can't say there was anything that excited me about this map at all and it would really take an overhaul to make it any better.
i think you have some good creations in you yet though, so don't give up
