Working in pen

While I have been planning  and drawing out my next watercolour I have also been working on another pen and ink drawing. The whole drawing is created with dots using a technique called Pointillism. This has taken me about 12 hours so far and I am guessing it will probably be close to 30 hours before it is finished. Its easily transportable though so I can keep it with me and draw at odd moments throughout the day wherever I happen to be.

I just love his developing expression. I wonder what he is thinking. Any ideas?
