I like it a lot that you used backlighting here....as it adds to the atmosphere...The vegetation is really nice as well...but it would have been a nicer image if you would have chosen a wider angle....that way you would have shown more vegetation for the deer to peek through.
I like shooting at f5 as it blows out the BG, but this narrow DOF often leaves part of the image OOF, as has happened with the doe's nose. Just a minor nit, but bothersome. I agree that the use of fill flash would have helped here. That said, I really like the image, especially the backlighting. Thanks for sharing.
