I thought it was pretty good.
I'd have called this "Japanese Love Lasers".
Well, maybe not. Anyway, it's alright, I'd say a little time looking into mastering wouldn't hurt, and if something ends up repetitive you can always alternate instruements for the melodies, or harmonize with an extra one, that never hurts, unless of course it sounds bad..
Please contact me if you would like to use this in a project. We can discuss the details.
