I like this capture. I've been shooting Dall Sheep in Denali National Park Alaska all summer and they are so much fun. They get the best expressions when they are eating and just looking around curiously. I think you capture the expression of, "what's that." I like how you captured his gaze straight at you. I think the background is somewhat distracting because of the hazy look of the grass so maybe play with cropping. I'm not sure what you're sharpness is set at but play with bumping that up and you might get a bit more detail on him. In the future look for them eating on grass they get the most akward expressions... Nice post thanks for sharing!
