Head Base Redlines Please!

So I recently completed a Fennec Fox head base and I was wondering if I could get any red lines? I tried to show the little 'stop' that they have and tried to put in a sort of cute smile. This is my first completed/successful head base and I'm pretty proud of it! The one thing I can't seem to fix is the mouth. From the front I think it looks pretty great but from the sides it's a whole different story.
Any advice/red lines?
