The beauty of this, for me, is that this is not an image of a deer, but of animals in their environment. The whole is greater than the sum of the parts (I hope that's an expression that people in other parts of the world understand).
It's just sublime. Plain and simple!
I agree with all of Donald's comments and hope to use your image and his comments in my future wildlife photography. Now that said I look at your image and then your profile and wonder where you took the photo, where you live. I see so many people only partially fill out their profile and wonder why.
Another agreeing with Donald. Just looking at the picture, if you had the longer lens and got a closer up, just looking around the immediate area of the deer, you would get plain trees in the background with no color and possibly a small pine tree tilted over being distracting. This way, the green of the trees adds to the image as do the large tree trunks, the hilly slopes, etc.
As always, love your deer shots. The taking a wider more distant/landscape type seems to be new this year as I remember mostly close ups before but I must say I am enjoying them just as much and sometimes more. Keep it up Steve!
Steve you ought to look into producing a calendar or two with some of the absolutely beautiful deer images you have shot!
