First, I know nothing. I have never been asked if I wanted to sell anything.
So I am coming from a place of pure ignorance and thus am free to have opinions without any basis in experience.
I think some of your work is really terrific but not specifically sell-able without something of a reputation.
IMO, until one gets to a place where one's work is 'art', the main kinds of pictures sold are pictures of people.
I love your pictures of people but they aren't traditional.
Your 'classic' portraits are art school classic, IMO you need to get closer to what the average schmo thinks is classic.
I think you would benefit from having a few large, sharp, color pretty pictures just to show that you can make people pretty.
