As per your request. This is my fav of the four you asked about in your thread. I would have voted this a 7 maybe an 8. The high key background works and the red wagon adds a nice splash of color, it's alos nicely composed. I do think it could be a bit sharper, maybe a bit of USM. I do think that some may have had an issue of having a hard time to make the eye connection. Your model has dark fur and dark eyes, which makes it hard to light them properly. People instinctively go to the eyes of a subject and want them well lit and sharp so they can make a connection.
Lucky pup to have his own wagon! And in such a nicely complementary color to show him off properly. He doesn't look like he's entirely comfy with being squished in the corner and hanging over a little. Still a very cute shot.
