Percy Practice Picture

I've been trying to practice my... style. I'm trying to differentiate each character, but varying their facial features, body structure... etc. I always pictures Percy as a tall, scrawny guy with round eyes and an oval shaped face. I wanted him to be tannish, but not as tan as Annabeth. His default face would be, of course, confused.
