Needs some work
Well it's obvious that you put effort into the song so.... Things you could improve on are combining your synths and transitioning from one to another smoothly. The kick in it isn't as dominate in most trance songs so I can see how you are confused between trance and ambient. I'm not really sure how to classify it myself.
Anyways all said and done it's different but could use some improvements. Keep working on it and you'll get the hang of it.
On your free time check out my new song {Take Me Away} and tell me what you think of it.
