The roof is sharp but you could add a little more depth of field. I am not sure that is detrimental to your file. The shadows are a bit too dark - details is lost. The photo is a bit too cool (blue). Add some warmth. It is also slightly grainy. Zoom to between 100 and 200% to inspect and correct what can be corrected and resubmit and see what happen.
Unfortunately, because this was taken with a smartphone - they have small sensors - when you enlarge them as the case may well be they show JPEG compression artifacts like so:
The image quality here isn't that good. Good enough for screen viewing, but not for large displays or large prints.
