This map is very promising. I especially like the initial detailing of the brick building outside blue's spawn - it's an interesting direction to go in for sure.
There are a few things that could use changes though. To start, your door shutter speeds are quite slow and it's easy for the faster classes to bump into them when trying to get through. 500 hammer units per second is a good speed that avoids this issue without looking too ridiculous.
The map is also quite dark. The inside areas are fine but the outdoors one could use with a brighter or perhaps less tinted light source.
Finally, the route through the brick building on the left from blue's perspective is too long and narrow to be of any use. If you find a way to shorten the corridor or to turn it into more of a gameplay space rather than a route it might be more fun.
