Yes, everything that is more lit draws the attention. intereting clouds. To draw more attention to the tree it would need to be brighter than the sky, but thats not easy to achieve with a landscape.
But I think this is a very nice shot, its great. Down to the tree not being in the center. Good dof, sharpness, nice colors of the sky and the hills in the background.
Also of interest is the root of the tree which is stretching into the right side of the picture.
In short, its great. I dont have anything to suggest
