No need to say that with such contempt.
What you have here is a solid portrait, and is very saleable. We see a lot of "creative" work on this website that my be "interesting" or "different" but isn't going to make them any money. If your goal is to make money for new equipment, you're on the right path.
As for your processing, before tinkering with the color...I'd recommend that you clone out the bit of hair that protrudes past her right cheek. It looks like she has a huge hairy mole.
It's a beautiful portrait, and your other processing methods look good. I'm not a huge fan of the blue. #4 is my favorite.
