Congrats on the sales Mike
On my last holiday to the US, I visited a place called Sausalito in San Francisco (just over the golden gate bridge). The place is a small mecca for artists, with dozens of small art galleries. Now I'm not an art sort of person, but I enjoyed walking around in these small galleries for a few hours. Several of the galleries were dedicated purely to photographic art. I'm not saying that you should have your work displayed in an art gallery, but you do have a good eye for a great picture, and this is proven in your work to date!
