By clipping he means body parts touching each other and going through each other, instead of colliding realistically. (i.e. the girl's foot clipping the man's foot in the reverse angle shot) But aside from this minor issue, this is a really great first try! :o Probably the best first try I've seen on this site. Really great that you started off with the Graph Editor, it makes a huge difference in precision. Anyone else having doubts about using the GE, take a look at what Wankar's done here.
