I'll just give a feedback about the general texturing of the level and the mood ;
Some places works very very well (http://i.imgur.com/KsEQLw4.jpg / http://i.imgur.com/lNAFIRB.jpg ) because of the simplicity of the materials and the good lighting setup.
I'm not joking since I know that you are using template texture but honestly, these works far better than some of the custom noisy texture you put... like the stone road ( http://i.imgur.com/ORiraBs.jpg )wich doesn't match with the rest (different color, fat join) or the ceiling http://i.imgur.com/xyUprJ2.jpg) is certainly representative of a bigger problem in this map : The artistical direction seams to be confused. On 3 Different screens, ([Blocked Image: http://i.imgur.com/KsEQLw4.jpg] , [Blocked Image: http://i.imgur.com/xyUprJ2.jpg] , [Blocked Image: http://i.imgur.com/2ZwpvZL.jpg] ) I see 3 different maps and it gives the sensation that each rooms are worked very independently...If your map was unified on this point, you'll certainly gain like 1 month of development and lot of quality improvement.
For the next Step, I would suggest you to start with temporary quickly made textures before creating the final asset and having to retake them.
