Have to agree about the eyes. If they're sharp, even with the same depth of field, the nose would still be acceptably sharp.
That's a training Haltee (or some such) and not a muzzle, is it not.
Give Cocoa a chest rub for me, and clean his/her eyes :-).
Also, if Cocoa is a Black Lab, a touch of Contrast and some negative Gamma (reduced brightness) will enhance the Black.
