Well done. I think the processing works particularly well on this shot but I'm a sucker for HDR. The placement of the tree in the frame is just right. I'm giving it an 8.
Would that be the James River??? I live just a couple of miles from the James myself (but it's nowhere near this size here). Great tones and composition. Really a beautiful shot.
nice sun rise shot. I would have been tempted to crop out some of the sand at the bottom as its not too interesting well besides your footprints :) Maybe try getting closer to the tree. When you darken your sky you need to try to get as close to the tree as you can otherwise you get that halo effect, try using a soft brush in photoshop or a mask.
