The photo is a lens seller, but it is also an example of when things just come together and produce a perfect situation. Just a small variation and the picture is totally different in character. No criticism, just a general comment.
Not to hijack this thread, but thank you for the kind words on my 50 mm portrait photo!
I agree that MU/hairstyling, environment and model play a significant role in the feeling of this image. The shallow DOF and OOF area however wraps it up.
