ears are always a pain to stitch.
i dont even bother paying attention to the topology in ears anymore. as long as it looks good. if it were me i would eliminate a lot of those edges that are so close to each ther where the ears are connecting to the head. ngons work well in an area like that.
here's my contro to this. its my current wip. typical comicbook hero head guy.
i went n-gon crazy in areas that stay planar all the time, or areas that normally have funny creases in the face. it easier to get away with them that way.
