That was good. I can see progression! I think that you should tell your cameraman to stop wobbling. I liked how you added other stuff than just unicycling. Try to be a little bit more diverse in your tricks. (Try hopping up a curb!) Also, try and edit out the "not doing any tricks" sections. Ex, it takes fifteen seconds for you to go and actually do the trick. This makes the movie a little bit more tedious.
You don't need to. Just aim the camera on a trick you are about to perform and then do it. No wobble. For the stuff around your house , you probably wouldn't need a tripod. Just use the stuff around you.
