Things you gotta improve:
Camera Work - I recommend you BezCam.
Shaders - Use different shaders just so the quality of the video will be waaay better.
Effects - Some of the effects you used were poor, mess around a bit and make a kind of effect that no one have ever done.
whatsong?
Its really good and you did have sync, now i dont want to repeat about the camera.
What you should do is fade transitions and change shaders a little.You dont have to use crop
for every hit, if your using sony vegas there are tons of effect and tutorials on youtube for them.
7/10
PS: i loved the head passing transition at 0: 38
