The subject of the three prints (from 1995 resp. 2007) is abundance and sobriety. – But for me the prints are more about the difference between effort and art.
The comparison was a harsh disappointment. "Cutty Stool" was my first (within five minutes made) drawing on a computer (after a few test strokes with Photoshop).
It took a decade for me from the first use of a computer to extended knowledge in 3d modeling and imaging.  "Set of Chairs" was the first large-format rendering I made. – The print looked the better the more I reduced (or even removed) the 3d properties in the final image: surface texture, color gradients, perspective view, light effects, high-resolution etc.
Sad. It had cost a decade – for nothing.
 At the same time I had to work for the money at building sites.
