Very nice composition and clarity. The colors are nice too. I'd use photoshop on the dog's tongue a bit to remove the shadow and saliva bubbles. Other than that, the photo is great. 8
I like the dog's expression, but I can't really see it a a magazine cover. The background seems distracting. Focus is nice, good color. Composition seems wierd.
Wow! This is an awesome shot. This is top quality and pitch perfect. I'm going to give you a high mark; however, you may find others will mark you down for having a horizontally cropped image instead of a vertically cropped image. IT seemed to be an issue in the last magazine challenge.
