A great image with a good lead in your correct to include the 3 ravens I particularly like the way the road leads you to the tree disapearing into the mist.Not for me to really say but I think I would of increased the contrast a little. It would make a fine Pink Floyd album cover methinks.
It is a really nice image the only thing that I would do with this is to clone out the yellow catch lights in the background.Also the composition would of been helped by placing the plate in the centre just ballance the image.
I like this image think I would try and saturate the foreground a little as it looks a bit washed out,usually people over cook HDR images but not in this case.
I feel it needs that bit more of a blast in HDR
