Adjusted levels and sharpened a little. Had taken several seven shots and although this was not initially my favourite, I liked the effects and detail when converted to B&W and slightly adjusted.

Huh? it appears that there are several that are opened. Too many mailboxes.
Too much contrast here, loss of tonal range. I think you might have done this as an artistic gesture. If you have, then it doesn't do it for me. If this was not your intention, I can suggest that you be more careful to preserve the tonal range. The tonal range can be obliterated by aggressively narrowing the levels, or increasing the contrast and brightness too much.
