I am going to assume that it is still in developmentand you want comments on how to improve it. Maps take a lot of hours of work and any any one commenting here who has attempted designing a map will appreciate that effort it takes.

So although you have worked hard on it you still need to work some more. I would recommend getting rid of some of the electric meter mapmodels that you have down one of the alleys. Some of the areas with the gray wood texture looks a bit out of place. The Consider how some of the door texture ares could be improved with extra details, they are looking a bit plain imo. Also consider adding more detail across the floor area of that large area.

The size of the map is good and some of the flow looks ok but I can't comment on that really because I haven't played it yet.

I remember that I was around when you started working on this somewhere on a public server, btw...

Jiba already pointed out several weaknesses, so there´s not much left to say...

First, you need to fix your package.

There´s one major weakness, in my opinion. The layout.
I already tried to explain that ingame. You tend to build huge one-room-halls which are supposed to be houses or factorys. To me it feels like I´m running around between huge cubes or something like that. I´m seriously missing the 'urban'-feeling. It doesn´t feel realistic to me, so to say.

I highly recommend drawing little layout-sketches before you start mapping.
