Weathered tree growing out of rock

I really like this tree, and the cloud shapes almost seem to join the curvature of the trunk and branches as some sort of pattern.

 

I almost wonder about the tree's placement though, when it is such a directional object with its growth to the left. I might have put it a little bit more to the right, to avoid the lopsided feel of this composition.

Golly, but doesn't this image want to fall over to the right! I know you don't want to "center" the image, but I'd think perhaps swinging the camera a little to the left might help. Just a thought...

Simple strength. Nice placement of the tree, but the centered horizon needs repositioning in this image.

What lens? I'd guess a 24 or 28?
