Not bad. I like how you experimented with some sounds. It has a strong beat. You already won first price for most original work. For sure, I never heard something like this before.
I really like the synth in the start and in the middle of the song. Really fills up the beatboxing stuff.
The part at 1:32 is catchy and sounds cool, only the transition to that part ( at around 1:31 ) is kinda worse. At around 2:00 and further, the song gets messy and I actually lost my interest of listening till the end. But oh well, I did listen to end. I was disappointed because you fade it out, lol. I expected a 'funny' and cool ending.
Anyways, don't hate on my harsh review. I liked the song! (:
