Beginning Sketches for two illustrations depicting "inner thought/voice". The first is 'stairs of mind', basically, revealing a dark basement, a very thoughtful/logical middle floor, and a dreamer on the top floor. 

Below are a couple more sketches for possibilities for illustration two.

Next are a couple of rough color versions of the sketches.

Here's the progress on the second illustration.
