Hi! Thanks for the feedback. Really appreciated!
B&W: I did try it and liked it, but I wanted to try color for you guys to rip apart as I usually shoot B&W film so B&W is something I tend to do more often. But I agree, it is a good shot for B&W.
Color: I do like the punchier example, although I didn't want it to make it look too "fake". After all, it was a very cloudy day and I didn't want it to look like an HDR shot or something like that. A bit of decay is what I was going for, which matches the subject and I guess is what Rexlawyer liked about the washed out color. In any case might adjust just slightly as comparing side to side now the original may be a tiny bit too dull. I'll be happy to hear further thoughts on this, as I think it is an interesting subject nowadays, where cameras seem to over-saturate everything and we can punch in as much vibrance and color as we we want into our images.
Crop: I love it when there's different opinions! Thank you both! I had some more frame around it but lost it when correcting a very badly levelled horizon... I need to improve this. Glad to see there's different opinion and, to some extent I agree with both, so will probably leave it as is. I agree there's nothing really going on in the background but I think it does add a bit of context to the shot. That said, I had toned it down a little so it didn't pop-up as much (one of the buildings is white and was distracting).
Here's my version of B&W (I like contrast!)
