With only about 30 seconds to get the shot, you have done well. A little bright at the sun, I would like to see the ones that came a littl later. I presume it is sunset, earlier if a sunrise. 6
Great colors. Just the slightest bit hot though. I think I might've got a little less mountain or hill and a little more sky. THe hill is not adding much drama to this photo as I think the sky would.
Nice idea, using the colors of sunset to show air, which is normally invisible (in fact the clouds are water, but who's complaining? I think somewhat less black at the bottom of the photo would bring the sky out even better.
