The dancing performance in film ' Toy story 3 '

Just search some highlights of animation about toy story 3.
I want to learn some exaggerated body language from that two clips.

Clips 1.

That was amazing dancing performance. Even this shot only spend 53s, but there has a lot of  actions and very complicated.I am really like the hip swing  when Buzz dancing, the detail  make the character with more personality. In this clips, Buzz want fall in love with the girl, so he show more of his excitement when he dancing for girl. The timing was being good controlled in this clips. 

Clips 2.

This is a period of pas de deux. Finally, the girl accepted the love from Buzz. So, this dance is very cheerful and passion. The action and movement also difficult and complicated. It's hard to make the two people dancing like this period.
