Somehow I seem to recognize some of the fellas: like Larry Laffer and some pirates from the Monkey Island series (like Largo)...

excellent work. makin charicature look easy.

 Full points. All of them looks great. The shadows are perfect.

Cool style!

 Ah, en cuanto vi las caras fui a ver tu perfil y efectivamente eres de España!, me recordaron de algun modo a los comics de mortadelo y aquel estilo, .
