The only useful comment I could make for the moment is the only thing in the map that distracts me; the shadow from the bridge on that wall. Sorry, but it is way too obvious that the light entity is very close to it because of how that shadow is being cast, try making the mapsize bigger and moving the light up further if you insist on using a point light. Otherwise, you may consider using skylight.
Other than that, the map is a bit flat and could use more depth and texture. I think you may have tried to overcompensate there with fancy geometry structures and mapmodels which have little to no value as far as gameplay is concerned. Unfortunately, the scene does not look real or alive to me at all, more like a box filled with a few trinkets.
Okay, reading that sounds real harsh I know. That's not the intention though, I see some really half decent ideas in this map and think maybe if you decided on some sort of architectural structure before making little trinkets the map might have more theme and life. This map is probably more a good lesson for you to look at what you did wrong and how you could do better.
