3 - For a Pet Portrait, whilst not a bad action/character shot, the blur/issues dominate too much in my opinion and I'd rather have seen a 'still' shot.
To me, a portrait has controlled lighting and setting, and both seem to be missing here. I think the face should be the focus of the shot and the first thing I see here is the middle of the body, then I look at the legs, then look for the face.
Beautiful horse. Even though I realize this is an action shot, I still believe the overall focus is blurry as the backround is blurry also. There seems to be no stop motion or panning.
