This began its life as a magazine illustration; but after the magazine was published I went back, made some changes, and re-rendered it at a much higher resolution for use as a print. As always with these images I did considerable overpainting in Photoshop once the rendering was done, and it combines several (um, maybe three) rendered layers that are composited together.
