John,
like Julie, I prefer #2 but 2 & 3 are both winners depending on whether you like high-key or low-key. The lighting looks spot on to me. Although I might punch up the saturation just a bit. But that's a matter of personal taste.

As for the dog, great expression but don't walk him in a strong breeze. Those ears would make the Flying Nun envious .

Overall, nice job. Did you shoot these solo or did you have an assistant?
