Fallen cloud

I have been fascinated and very impressed by the shots of asphalt on blipfoto recently (yesterday's by Red is a perfect example). It's not something I have ever really looked at with an artistic eye, yet you guys seem to make it look very appealing! So today I had a little go myself. I've cheated as the asphalt isn't the main focus really, but I'm not brave enough to go for a complete asphalt shot yet!
