Good
It's a good song, I have to admit, but in future songs I'd like to see you drift away from using defaults from FL. I know how hard it is to get your own sounds. Try Hammersound.com (they have hundreds of soundfonts :D), and freesound.iua.upf.edu's sound database for some interesting samples.
The default FL sounds is all that bothers me about this peice. I think you're doing a really good job. Keep up the good work!
