USE A LIMITER!!!
But it is a pretty good ambient song. Sounds like something from Samus, no lie. Woah dude, I really like that plucky sound.
But, like I said, you need to start mastering your songs. Try using Fruity Limiter on the master channel and play around with the gain and the ceiling. That will help you out.
Maybe even EQ'ing it will help out as well. Ah who am I kidding, EQ'ing always helps out.
Nice song, but it didn't really go anywhere. It just kinda stayed in the same state of mind. I do like your effects btw, they are pretty damn cool.
