Ink and pen thumb portrait artwork

This clumsy and stilted portrait of a thumb was inspired by this more graceful one by Sergio Aquindo. Which in turn was triggered by an anonymous one he saw in a Parisian shop window. Just as Sergio suspects about his own, I feel that this fat finger of mine does not say all that it should. What's worse, it may end up revealing some other things that I have always tried to conceal.
