the first one looks best, you may want to bring the eyes up a bit so the distance between the pink accent and the eyes is the same as the distance between the eyes and the new darker cheek section. just for consistency.
the second one, i really like the idea. how youve done the eyes is actually alot like my own head. where you suggest where the eyes are, but theyr not actually eyes.
but the same criticism as with the first version, bring the accent and the cheeks up to make the eyes a little thinner. where you have the eye accents, it sorta eliminates the need to have the first ones
my main thoughts on having thinner eyes, like in my example and my explanation is because of the pink accents thin lines compliment thin lines in this case
