On Tippy Toes

I took a series of images of this young buck feeding on new leaves on what looks like a walnut tree to me. This behavior of deer is what leads to the so called "browse line" in areas frequented by them. Their continual browsing on the green vegetation often leads to an obvious lack of green vegetation from ground level to as high as they can reach. I was struck by how far they can extend their necks when reaching for these tender morsels. Of the series, I liked this one the best as the lighting was nicest, the tip of the tongue was showing, and he had a nice bunch of leaves ready to tear off. I thought the vertical worked best in this case as it seems to showcase the "long-necked deer" the best. You may notice a slight difference in the images as I forgot to save my initial work so had to duplicate it as close as I could for the larger version. Local wild deer. About 50% of full frame. Comments, suggestions, and critiques are welcome.
