After looking at it a while, I've decided I like it as is. Some of the suggested crops have merit, particularly since the foreground, the mountains and the sky are all dramatic and potentially compete for attention. Which brings up the question, what is this picture about? But I think an acceptable answer is that it's about all those things coming together in one place. Given the presence of those strong elements, I might be tempted to clone out the branch, but don't consider it mandatory.
Possibly more critique in this thread than you were looking for, Pramote?
