Have You Hugged Your Robot Today?

This is the only picture I have posted that has not sold, and I don't know why. Maybe you can tell me. Is the drawing too suggestive? Is it badly drawn? Is it because the lady is naked? Is it because the robot is blue? Is it because people just don't want to think about loving their machines? I would seriously like to know what the problem is with this image, because I thought it was really funny, and I was very disappointed with the negative reception it received. So please comment. Thank you.

This drawing, which I sold to a dear, close friend, is called "Stone Woman Road" It is finished in Derwent colored pencils. I like the Derwents because they are very light-fast. The paper is also acid-free and very archival. This drawing could last in its present form, for many, many years, which is probably more than I can say about myself.

This drawing is an 11" x 14" watercolor called "Desert Solids". This drawing sold on eBay.
