MAJOR PECS expressions

As I was sketching out his expressions, digitally with a wacom tablet, I encountered a problematic detail....his nose. Originally I was going to have a line there for his nose under the mask, as in the top left expression. When I tried different expressions the nose got in the way. So I just got rid of it. He can still have a line there for certain expressions, if the nose line does not get in the way. I actually like him better without the nose line, it allows more freedom of expressions with his eyes.
