So in the end it's approaching a crescendo, I suppose you could carry it on. I wouldn't recommend dropping the base just yet. Maybe the whistle sound could have a solo... I dunno, I'm not the musical genius here :)
Actually it's just a draft so I haven't written a part 2. I just got stuck at the end, but I liked it so I published it. If you have any ideas for part 2, that would be helpful! I'm glad you liked the synth though!
