What do you mean to say? WITH editing done, the tree would no longer be there? Wouldn't that take editing a little far - as you could have stepped to the side and take a photo of the sky without any bit of tree in the first place!? !?!
(Well, actually, I'm sure you don't mean to say this!)
The sky is a lovely blue and I feel the remaining reddish-brown leaves in the tree provide a pleasant contrast. Only little bit that might want to be cloned out is the evergreen on the right.
