Eeek, its not linked up to a map in his profile...insanity!
Looking at the screenshots again, there are definately areas which could have used work, but I appreciate you were working to a deadline. The harbour is the primary area of concern - the wharfs are extremely boring and unrealistic. How did you do the sea? Is it a skybox, or is a a hugely stretched texture to suggest the scale? Or is it some crazy combination

It looks good in the screenshots, but if its a skybox it would look wierd as it wouldn't move as you move :sad:
Another issue is that the map looks good but I think thats mostly due to the textures. Thats not a bad thing, especially considering you made them yourself, but I do feel its rather bland architecturally in parts. Most buildings for instance are just nicely textured boxes.
/me reminds self this is the HL engine, and thats to be expected in a town map
EDIT: My new lines still aren't actually coming out as new lines! I'd best shimmy over to the suggestions and bugs thread.
