Okay so, I took a quick look at your sketch.
First of all, what was good?
- Love the camera quality, if I'm not mistaken you have made a big investment there
- The idea is good, although might be a bit overused
- There is good humor in there
What could be better?
- Keep the audio consistent when making those over shoulder shots when filming against the wooden "fence", it is disturbing to hear the background noise change every time you change angl
- When doing over shoulder shots, cut the audio before you cut the video, to make the transition more fluid. Check for example "Top 5 tips for filming dialogue" by FilmRiot
- The video loses interest towards the end because of the repetitiveness, keep this in mind. Think "How can I make this subsketch different"
Hope this was of use.
