sky >> I like big sky >> art?

I have always been interested in the weather especilly the effect it has on the sky and the sea. tonight we had a really excellent sky I watched too long and actually forgot to take pictures, well until it was a bit late but still you get the idea from the images posted. the one on the right is taken standing on my front door step.
it is such a shame I am often so disappointed when I search for good landscape/skyscape pictures across world of digital land to use in project with my students. so many the web sites you come across tend to be too text happy and if not just want to sell you an art print!

art print I am really unhappy with that term it is almost suggesting that the photo prints they art selling are art just because they are pretty. tell you what a simple look through any number of flickr accounts (of supposed amateurs) will show you more 'art' and a some (most) of them you can download and use for free, obviously following creative commons rules.
I like creative commons I know on this blog I withold the use of my work for others to make money from I think that is fair enough, however on my flickr I will happily allow (use as long as it is credited) to make as much money as they can.

I had to post this last image (sunday afternoon on the A30 near bodmin) just because I love the neat arrangement of safety cones, but it is an image it isn't art is it?

special note: I do realise that art is a definition I am not really feel qualified to make. having never considered my self an artist I do feel qualified to make judgment on what I see, and think about what I am looking at.
