C&C per req:
To be brutally frank, this does very little for me. There's lots of potential here, but I'm not sure that you've gone about it in the best way. First, there's no clear point of focus, and it looks like there is a WB issue with the pinkish sky (easily corrected in post) as well, the nearly blown, featureless sky is less than idea. The tree roots would work better if they were either all in silhouette or all correctly exposed. (I would go for the silhouette option).
There are a couple of options here: 1. Use your flash to provide light on the roots and help reduce the dynamic range of the scene, 2. Expose for the sky and render all the roots in silhouette, or 3. Shoot 3-4 images and increasing/decreasing exposures and combine with software for an HDR image.
Just my $00.02 worth - your mileage may vary.
