If the map is complete, then check out Global Assault. They are a big
map library, and will host your map and give it a quick review most
likely.

Judging by the screenshots, I'd say the main point you should focus on
improving in future efforts is your lighting. Currently you look to be
relying entirely on the light_environment with the odd street light
dotted around, and even those don't provide the map with much lighting
contrast. Don't be afraid to place more light fittings around the map,
even where they might seems somewhat unrealistic, in order to get more
variety in brightness.
You may also want to try and break up the repetition of both your
architecture and texturing in places. You appear to have an exterior
wall that doesn't change much as it encircles the level. To introduce
some more interest to it, you could have built a few buildings around
the edge that are inaccessible, yet bring in much more variety in
height and texture. As a more simple improvement, you should look into
using overlays on the walls to add surface detail with very little work
required.
Not at all a bad effort by the looks of things, its just a tad on the basic side. Good luck on your future efforts :smile:
