pretty nice

Awesome!

thanks my man, im just getting started and i want to do plenty more mapping im starting my next map next week

Very good for an early map! Excellent use of moving water. A few bits of critisism (I'm just trying to help):
You should use a model instead of a texture when it comes to ladders; it looks much nicer.
Consider adding an env_sun to your map. All you have to do is add that entity, and make sure its values match the ones in your light_environment (I really like the lighting, btw).
The cliffs leading up to the walls of the map (not the cliff at the side with spooky sewer) shoot up too suddenly, causing VERY stretched textures and un-naturalness. I know it takes a while, but making the cliffs gradually build up a little bit would make your map look heaps better.
These are just suggestions I thought might help. Good luck in any future mapping! :D
