My Final Face 5

Done as part of a practice session with poses of 30 seconds in length. My current goal is: Draw facial muscles with cartooniness, but with realism and humanity in emotions and acting. I'm done, and I'm leaving my vacation day after tomorrow, now, I'm going onto some Scenes and Environments. What do you people think? Did I do an exceptional job, or, could it have been exceptional?
