Este señor fumando llamó mi atención por la cara de susto, parece que le da miedo que lo pillen fumando o algo así… Es un retrato al carboncillo muy simple, otra vez con fondo oscuro.

In English, please:

This old man smoking got my attention because of the frightened face, seeming as if he were afraid of being caught in the act smoking… It’s a very simple charcoal drawing, with dark background again.
