I really like your composition, using the old branch in the foreground is great. It feels too dark though.
The other issue is the halo around along the horizon and especially the West Mitten. If there are halos in an image, B&W will make them more prominent then color. On an image like this I might use the Quick Selection tool to select the sky, if your intent was to brighten then ground then I would inverse.
There is an issue with Uploading Photos (attachjments). I am not sure what the problem is, and I am looking into it. You can still try to Create your Threads and Upload your Photos, but it is hanging up during the Upload.
