I like some of the melodies, but none of them really come together to make one song. They all sound like different melodies to different songs. Nothing blended, and it ended up giving me a headache.
But on the bright side, all the melodies were on beat.
Overall: I'd remake this song with the same beat, but give it a definite structure. You might be able to keep the melodies but you'd have to organize them and blend them, which seems like a bit more trouble than it's worth.
