Firstly, Please upload to some Tremulous Map Repositories (TremCentral, Random Key Whacking).
Levelshot: Up to you but I, and most others prefer a levelshot that actually shows an image of the map
Leveldesign; This is little more then a random assortment of unrelated rooms. All of which are too large and open (Jettards :S).
Flooded room makes zilch sense (what is holding back the water?).
Please fix the screens/cameras, they are making me nauseous.
As Bissig said needs more detail (Eg, Lighting fixtures, door frames) and a wider diversity of textures.
