I don't often look to the sky for inspiration, it's usually just the thing in the background, or above the sea or landscape that I'm interested in. More often than not, in this country, it's bland and boring and leaves a massive white space in a photo that is otherwise interesting - bloody sky, such a nuisance.
Here are two photos I took whilst looking up, not at building, not across the sea, just up. I hope that they're still interesting. I know that I enjoy them.
