A born hunter...

Well-composed interesting shot with an intelligently selected caption.  6 from me. Best regards.

I could see this becoming a commercial image to promote some sort of hunting apparel or canine nutritional product. The only thing that I would adjust is the shotgun, as the strong line of the barrel pulls your eye from the dogs feet up the barrel and out the left corner of the frame.  If you had the shotgun resting on the bag, with the stock behind the dog and barrel pointing down to the left of the frame, it would provide a line that moved from the bottom left up towards the dog with the dog's head being the top of a triangle and the bottom right corner of the triangle at his left foot.  Oh, and darken down the top left corner a touch to complete the effect.  Gorgeous dog.
