Room for improvement
Repetitiveness works in ambient music, but only when done right. It has to be the kind of loop that puts you in a trance like state, but still changes enough to keep the listener interested.
This needs work, first off try experimenting with these free VSTs
-DSK Oranze
-DSK Keys
-Taurus
-FL Studio's TS404, you need to change it more, and add reverb! Don't be afraid to experiment
-ME80, it's not free, but it can be found... around
Try those, experiment, find new ones for yourself.
Always mess with reverb when making an ambient song, always! Delay can't hurt either, just mess with them until they sound neat. Don't overdo it, but don't underdo it.
Anyway I like to review on a review for review basis, so it would be really cool if you could review our newest song. :)
Thanks and good luck
