Good job! I really like it. My initial reaction was a look represented by a crossing of Duke Nukem 3D and Max Payne (but with greater detailing, of course) which in my mind is a good thing. For a first map this is a really impressive job, it still would have been if you had been mapping for your entire life. The only criticism I have to give is that the garage areas are too "blocky" and undetailed, the architecture doesn't fit in with the rest of the map and looks a bit HL1 with Source rendering. But apart from this I am really impressed, great job with the lighting and models.
