Here are some sugestions.
You defiantly put some effort into this piece. My only suggestions are that you ad more FX to the orchestral instruments. What tends to happen is that FL (Or any other program for the matter) will sound bland... adding reverb gives it a more acoustic feel and warmer sound.
Thanks for the review. I'll take that advice onboard for next time. I'm still getting used to Reason. I made this a while back and I really had no idea how to use it.
