Very true, popnfresh - my difficulty is that I don't market them at all! However, I'm in the process of putting a website together so maybe that might help - if it ever sees the light of day.
A web gallery is fine, but people who actually buy art prefer to see the work in person. If possible, I would recommend getting your work on display at a gallery. I bet if you showed your portfolio around, some gallery would be glad to give you wall space. If not a gallery, then a coffee house, library or some other public space. A friend of mine owns a bar in San Francisco and he puts up art shows all the time there. And he sells a ton of art, too.
