6 - Nice straight portrait - like to have seen a variation in lighting or using dof in a different way perhaps for more pop. Sunlight looks like itis on her neck.. so perhaps the potential was there for a variation, who knows.
Beautiful dog - I like the way her eyes stand out in this shot. Nice lighitng and composition.
I'm undecided on the background though, I wonder if it is too similar in colour to her, making the image overall sort of flat. Perhaps bumping the shadows and saturation would help to make her stand out more?
Nice picture, pretty German Shepherd. The only critique I have for you, is that the background is too close of the same color the dog is, and she is blending into the background too much. Other than that, good job!
