I think the first scene could use some more energy. Scene 6 needs to be more crazier. I also thought that when Gail and Salty are taking about Benny Good it would almost be like a little argument.
We talked about how your character moves. This helped me because I had to think about how my character would move her hands and what part of her body she walking from.
I think Gail wouldn't sit on a chair properly she would slouch on it, she would sit with her legs crossed because she is quit feminine. During scene where the classroom is crazy and all the kids are doing whatever they what she would sit with her legs up on Hobby or Salty's chair. I think this will work well because it will show the audience that the class is not doing what they are suppose to without distracting from the action.
