I like the color layers of the vegetation and the pose of the moose (especially the position of the ears between the antlers). Fur detail looks a bit softer than your usual offerings. Curious about your selection of 100 ISO given the resultant shutter speed?
Steve - this guy was so stoic and still that I had time to lock down the lens on the tripod and see how the 400 5.6 did with slower shutter speeds... I think I even used mirror lock on this image. So it was more experimentation than the primary settings of choice. :)
