Nice work, things are coming along well.
For starters I think the voice work is great, very cute and energetic and you're matching that acting and emotion well even if the lip-sync is a little inconsistent. You've definitely got some solid lip-sync work in there too. I particularly like that you didn't shy away from dropping the mouth corners to exaggerate some of the pauses and set up a little anticipation for going back into a big grin. I think that captures what a child's manner of speech is like as well as a good tip for animation overall.
To reiterate what has already been mentioned, the top teeth should be static in head, it's the "jaw" that drops down when speaking. I do think that you have some flexibility with a simple shape character like this though.
Kind of depends on your smart bone setup, but my quick fix thought for this would be to maybe connect the eyes and bow to the top teeth movement, so if the teeth go up the head sort of rolls back? Really depends on the look you want. (If your Smiley Guy family is related to the "Guy Smiley" family, a head opening a little more backwards at the mouth would be appropriate... maybe "Guy Smiley" is too old a reference? Is he even still on Sesame Street?
Anyway...

I don't
really have the time for it either, but it
would be hard to resist... The audio clip just sounds like a lot of fun to work with, like a fun fresh 11 second club clip... Oh, that reminds me that if you aren't already aware, it may be of use to you to check out
