The colour and detail feels a little flat in the top 2/3rds of the image. Nice find though. I would have been tempted to clone out bits and pieces from the foreground.
I see neither you nor your shadow in this photograph.
The placement of the tree seems a bit awkward. With such a simple composition, the rule of thirds is a useful guideline. I think you should have placed the tree somewhat farther to the left.
The tree itself looks somewhat washed out. A levels adjustment or some burning might have helped.
This has a haze to it that is a smidge distracting as it seems to blanch out the foliage of the tree. Probably due to time of day. I wonder if you used the burn tool on the leaves and maybe did some adjusting of levels?
