Not being funny, but that fisheye is horrible. Take it off and render and film in 16:9 instead of 4:3 (widescreen) as I think has already been said.
Less slow mo and black and white effects, keep it simple and to the beat of the music, you don't need loads effects for a video to work well. Oh and get a tripod
Other than that you seem to have a fair bit of control, well done for not just throwing yourself off stuff like i see alot of people doing in here.
