Very nice indeed, well detailed and good DOF. It is a beautiful creature I am constantly drawn to the muzzle and the eyes.
I can't help but feel however that the colour balance is a little on the yellow side
I like the way the subject enters the frame and background is truly gorgeous and smooth, buck stands out nicely.
Inclined to think that Jon could be right about the colour.. I think you posted an image recently where the colours looked more natural and the coat was less orange?
Face is sharp with good detail. From the aesthetic point of view I find the tongue sticking out a little ' too much ' but I suppose it's ok if you were aiming for a fun image
