I've always wanted to depict an interior scene in one of these dives, ideally painting on location, but that would not have been logistically feasible, so I've had to resort to multiple photographic references along with years of quick sketches of people at bars, cafés, etc...The first two images below are quick compositional studies in color, playing around with placing the elements and establishing light and shade and, of course, working out some basic color schemes.
The last image is the completed painting, a small piece, on canvas mounted on panel, 23 x 17 cms, or about 9 x 7 inches.
