Technique
You have used the dramatic lighting to your advantage in this shot by capturing the "rays" and using a form of backlighting to silhoette the branches. That sets up a nice contrast, and makes the sky look even brighter. Looking at your settings, I wonder if you could have used a lower aperture value and faster shutter speed. I think that might have made the branches appear more in focus simply because the slight blur they have looks as if the wind was blowing or something.

Compositionally, I think there might be a bit too much "dark" on the left of the shot. I think cropping a bit on the right and left, would make the composition seem more balanced, and complete.
You don't mention any post-processing, but it looks to me like you upped the contrast a bit, and it may have affected the clouds a bit too much -- there are spots on them that are a bit overblown, it seems.
My first impression is that this shot is a bit out of focus. Unfortunately, when viewing hundreds of shots, the first impression is usually what gets to determine the vote. The composition seems a bit accidental, and the clouds are a bit blown out in areas. Had a voted in this challenge, I probably would have given you a 4 (for the aforementioned reasons), and maybe a 5 because you did an excellent job of capturing the "rays" which is not always easy.
Not so much a 'boring' branch as a 'too far out of the shot so it becomes sidelined and could have been much more dominant' branch. Has potential to be a really stunning and suitable shot.
Great colours in the sky and the leaves on the left are strong. Would have been nice without the tree to the right of the picture and would have benefitted from the having some of the black space cropped from the left edge
