At one point, when younger, I did art while holding down a job. I traveled quite a bit in my line of work which pretty much dictated that I do "small" art; I lived in the South Pacific, Africa, and in Cuba for extended periods of time and lived at other locations around the world for shorter stays (I lived in exotic sounding places like Zakhu, Berbera and Olongapo... exotic in sound). After I stopped traveling, and working full time, I tried my hand at art as a full time profession but found, after several years, that art, though an amazingly entertaining profession, failed when it came to supporting a family, paying for the kid's college, paying for food, that sort of thing (all the more true during the "great recession"). I went back to work a few years ago but still made art. But, and for me this is good, my time has opened up and I have started back on art, and though not full time, which would be better, it is part time which will lead to full time.
Much of my earlier work was photo-derivative.... or photo-realistic. It was quite detailed and I enjoyed the tedium of completing a work. I am starting to shy away from the photo realism. Still, all my work is representational in some way. My most recent work is along the lines of cityscapes with an occasional landscape or portrait thrown in for good measure.
