The format of the canvas is 120x200 cm. After I projected and traced the lines from the 3D-reference I'm now mostly using the airbrush to shape the shadows.
In these three photos, however, I'm painting highlights on the edges of the cubes with a small brush. (Listening to Isaac Asimov's Foundation.)

Your art work seems like all in all, the combination of advanced technology, versatility, and potential for interactivity!
Just wow!
