Archetype or Prototype?

 

 Every now and again I take up graphite. There is something so satisfying about pencil on paper. HB2,

HB4, HB5. HB6, and HB8. Recently I have been splurging on filling up small sketchbooks that are half done or 3/4 done with these small faces. 

There is something so compelling about a face -- each so unique, each with its own expressions and features. The hard part is capturing them with any kind of animation.
