Trance to the max!
I've noticed that most of your songs are pretty simple (not a bad thing at all!!!) but what I think this song needs is some kick ass beat to support that awesome climax of a melody towards the end of this preview. Something hard but slow to show off the synth work. I hope that makes sense! I really like this preview and I can hear where I think it should go, but it's your creation so shape it however you want.
