Lovely composition and a very striking contrast. The trees are a bit blurry, suggesting the camera was attempting to focus on the sky, but otherwise a good shot.
I agree, the black clouds are very ominous, sinister even. It almost makes one wonder what goes on in your area at night to make it take on such an evil tint. Good job with the striking contrast between the bright colors, and the blackness of the night.
Wow, what an interesting shot. Reminds me of a portal. Hard to find a critique for this. Short of the focus issue, I like this and it does make for a great desktop! Thanks for sharing.
