Last one's unavailable. tho I don't get what sort of feedback do you want from us?
the basic gist of stunting is being able to find unique, innovative ideas & execute them accordingly, seeing as the first stunt is seemingly random & the 2nd is old, I can't really make up much of a feedback based on that.
Try watching some more vids & coming up with your own stuff & make a full-length video, then we can talk.
