This is an intriguing angle which is different from most shots of the angry sky. The absence of the horizon allows the viewer to impose their own "view" on the shot. The upper portion of the photo seems to imitate an angry face slightly tilted to the left from our perspective. The bright openings in the middle of the photo could be the open mouth. Then again ... perhaps I've had too much to drink ! 8-)
When I first saw this shot I wasn't too impressed. But the more I looked the more I liked it. I agree with Logit - it's a great angle and very unlike other sky shots I've seen on here. I really like the mix of colors due to the overlapping clouds, too. Nice work.
