All the Rotoball put together

I am going to talk about the changes that I would like to see made on other students animations. Well, first I would like for some people to change the color of the person or to change the color of the background, because I confused myself, I thought there was no person in one of the videos. Another thing is that I would like to take of some of the names of my classmates, that are in there video. In this interesting and awesome video there are some videos that I can't tell what the persons are doing with the ball or whatever object they have in their hands, I would like to make it more clearer. In conclusion all the video is very interesting, important, great and awesome, I really like it.
