Rick, the talent you have is unique.
The camera, lens, spot on the sidewalk, length of time there, software, etc., is great, of course. Your talent is expressed through the tools and material.
I, for instance, could stand there with the same equipment, shooting the same people, and do everything you do, and I know that I could not match your art. I don't have that talent and never will. I have other talents, as does everyone. Same tools, same material would equal a much different product.
However, your posting what you do and how you do it, and the product of your art, may actually help those of us that do not have your talent/experience to possibly become a little better, within the realm of our own talents. That is what this forum if about, and obviously, what you are about...
Talent is something you have or you don't. One may have talent in different area's, and excel there, of course. We can see examples of this all over the forum.
I have not seen images such as yours with that RickSawThat quality anywhere, and I do not expect to find them. They just have your touch.
You are unique. Thanks for sharing your images and posts. We are all the better for it.
I believe we all know you will be very successful wherever your art leads you, and will be in your fan section!
