Wonderful lighting on the walls, through to the, then, well lit passageway at the end. A very well made picture, in my opinion.
+1 to Donald.
But it could do with a little more contrast, IMHO.
Nice composition and interesting image. My sugestions are
Reduce the highlights to get more of the texture on the back wall (the highlights aren't blown)
Add a little more contrast
Add a small amount of perspective correction to the left hand side.
