Really like the color version!
I think that b&w could work too, providing a bit different processing... something more dramatic, with different filtration, to separate oranges and blues... the beauty of the orange reflection seems lost in the b&w.
I would go for an 8x10 ratio crop, which wood put more emphasis on the branch and get rid of the upper part, where there isn't much new going on. And once in the cropping mode, I would experiment a bit with crop rotation, so that the branch is more dynamically positioned, not so upright.
But all in all, a very good shot.
