From as far as ive seen its a nice basic for a map :D, but there still needs to be much work about it.
Maybe u could trim edges onthe ground (as example, a line), that would make it look a bit more full and decorated.

The lighting isnt bad :D, only u should use a bit more textures to.

The screenshot could get bit better, so without hudgun :P, but already nice u dont see statistics like health or armor.

The packaging could be better 2. Make a folder called "packages", then put a folder called "base" in it and then put ur map into that folder. After that, package it then.

1 question: what theme got this map (like egypt, urban, metal)?

i hope to see the improved version of this map :D (so i wont vote yet srry =s)

Yes, true.
I think this is a "beta". Thanx for the comment. I do what you want and i update the file.
The theme is urban/metal. My idea was to do a map based on a laboratory of area 51.
Downstairs the map is decorate but little upstairs.

Why you don't use normal mapped ans spec mapped textures ?
