Indeed a very good image but somewhat flattened by perspective. Bringing up the background may help but I’d like to see this in colour as that may help the eye discern more depth. It would be interesting to compare the two, as this image is otherwise well suited to the impact of b&w.
I think this one is my favorite of all of them - a bit of different kind of post work, to get the background to come into play a little stronger, and this is amazing!
