Shot this out in Calif a few years back. These make great subjects but one must really work at getting a good composition since there is alot of merging and extraneous backround material.
I can see where a sliver more on the left would be nice but it's not a dealbreaker for me. Gosh, that tree...wow! What an interesting subject and you did a beautiful job of finding just the right angle. Everything looks lined up and yet totally random. Only suggestion I can think to make is that there is a pretty obvious light/dark area in the clouds - almost in a diagonal line across the sky. I wonder if making that more of a gradual shift between the light/dark convergence would add or detract from the sky? Hmm...
