İ can only comment about the graphics for now.
First picture, i think there is a second light source in the room and it spoils realism of sun illuminating the room. I think you should disable the light in the room and just try to illuminate the room with sunlight.
Second and third pictures, i liked textures especially wall textures. Dirty walls fits in the scene atmosphere perfectly. Good job.
