fun photo. i think the lighting could have been a little better, but more importantly, the photo taken so there aren't things that distract you from the subject like the toy(?), cooler, or floor mat in the background.
Very cute dog! He looks pretty smug in his outfit even though he got it a little dirty in the front. You have him framed nicely in the picture, however, the cooler and doorway in the background are a little distracting. The focus is perfect and shows nice detail. Picture might be a tad on the dark side. Some adjustment in post-process could brighten it up some. As far as the challenge goes, however, my definition on fauna is a little more than the family dog...no matter how cute he is.
Nice shot. Can't believe people do this to their dogs (yeah, I appreciate it might have been dressed up for the challenge, which is cool - but people DO). Not quite within my interpretation of the challenge, strictly.
