Well, great observation by Kent and helpful to understand more what is happening here.
First, I like the image overall and, as you know, I am partial to BW. An especially good choice where play of light and texture are the key elements.
Second, I think Karen's rework moves things in a nice direction too.
Third, I was hesitant to comment initially given the positive feedback and not knowing the reality of the scene. Now that I know, I will be a bit more bold. I think the bright area introduced on the left side is distracting, pulling the eye in two directions. And it feels a bit odd, unnaturally bright. The idea/effect is interesting. So maybe pull down the brightness or alter the blend opacity a bit.
Fourth, I like the overall image a lot I think its worth the time for additional refinements.
