This is pretty sweet, and the lighting is great. Buuuttttt it would improve exponentially if you used multiple textures, the wood look is awesome, but it needs some changes in some spots. Maybe Stone bridge, or different floors? I don't know.
I didn't try a fireplace cause you told me too, I tried it earlier. I completely surrounded a log with stone, set it on fire, and it still jumped 4 air blocks to the walls. I exited quickly to avoid losing a day's work.
