I like the shot as well. For me, lol....given the framing, it's the right edge as you hinted in post 3.
My eye would have loved to see some plain blue sky on the right edge instead of chopping through the clouds. Visually, it would have made the image more "harmonious".
But sometimes...often actually, you can't always git whatchoo waaaant.

Given the title though I totally see what you were going for. Imo, the panorama in this case is detracting from the theme of "evolution"....If you cropped out the right 1/3rd (or so) altogether, for me the image is stronger. The way it is now the shot is too much about the clouds...when really, the shot is mostly about the trees with the clouds as accents.
Feel free to tell me I'm way off if you think that i am.
Hope that may help - Marko
