Great subject matter for tones! Looks to me like you nailed it...
Took me a sec to work out what I was looking at but when you see it it jumps right out at you.
HiHo, I do not use or know B&W. So, I'll just say it looks fine to me in tone. The subject is placed well for the amount or lens size used from this POV. I like it. The only minor change for me is the "tiny" item poking in on the lower right edge in the sky. A crop or clone of that spot will drop that item easy enough. Good to go otherwise.
