I had just finished playing trivia with and when I walked out of the restaurant, I was greeted with a really cool looking sunset and cloud formation. At the time I was trying really hard to figure out HDR and so I took multiple exposures of this. The reflection is due to the roof of my car, which is where I had the camera sitting when I took the pictures.
The sky really was that color. I might upload one of the originals later for comparison.
