This is a lovely shot with heaps of atmosphere and interest in the clouds. However I think it would have been enhanced further by cropping off the bottom two thirds of the dark foreground.
Don't really like the positioning of that bush - too central for me - I would have wanted to use it to frame the brightest portion of the sky and to be more strongly silhouetted - which might have allowed a shorter exposure to prevent the burn-out as well. Still a good image.
Wonderful colors! Those clouds look extremely stormy and wild. Good capture. I would have prefered to see the tree either more to the left or to the right instead of being exactly in the middle though. Well done.
