I don't have a strong feeling about the tilt. My issue with this is that there's too much sky and foreground, especially the latter. The building is interesting, but is sort of lost. The better shot here, imo, would be a horizontal taken from a little to the right of where this was taken, and at a slightly longer focal length so the building is larger and the far end doesn't disappear into the distance. Try some different things. You will get a lot of opinions on here, but we all have a different take on it and want to show different aspects, so you have to find what works for you.
