You be clippin' balls!
Either your compression (or lack of it) has you clipping pretty much from the start, and it leaves the whole track sounding fuzzy. Also, it tends to get very repetitive for 4 minutes of the same lead with random voice clips (of varying quality) throughout. Sort of sounds like you just played with the preset voices on a $80 yamaha keyboard. It's not bad, but I don't really see a whole lot of creativity in this.
