I prefer the B&W version as well. I don't think colour adds much to the image, for me it gets in the way.
What is the photograph about? My eye is drawn immediately to the light patch above the tree. I'm lead there by the diagonal lighter water to the right and by the sweep of the clouds on the right. The next place I'm lead to is the dead wood on the left of the tree. I think the curve of the tree is attractive and is echoed elsewhere in elements of the image. Could I suggest that bringing that out a little and if the tree is the subject then redirecting the eye there?
