No I won't blast you for that but it wouldn't hurt to get one of the horizontals straight, either the line above or the one below the sign, it should help.
I will blast you for the perspective though.
Shooting down on it just diminishes the building so, unless you're going for the toytown look, I think that was a mistake. It also has the consequence of giving you too much sky.
By the focal length you entered I assume you were using the kit lens. So why not shoot from the wide end? You could get up much closer and shoot up, that would make the building loom much larger and blot out the sky. That would also probably emphasise all those off kilter lines making it look even more interesting.
I'll tell you what I do like, those four windows with the 'Y' shaped wiring in between them. Take a crop of that and I think it makes a great picture on it's own. Just play around with Levels and Contrast to make the wiring stand out as much as possible.
