Pretty good, well arranged :)
OK...
starts off pretty dark, liking the mood, the lead synth is pretty bad sounding, but not due to your work, simply need to get your hands on some better vst synths, the melody is great, just the sound itself. Bass as well, same problem. Purcussion, I sugest getting better samples, as I notice your using all FL standard stuff, so I'll not ramble on more about it. The arrangement is pretty standard for trance, works well, the melodies in this are pretty good, the piano adds a nice touch.
Likes : The Melody, very well done
Dislikes : The pure "FL"ness of it, if you were to redo this with better resources it'd sound great.
Improvements..
Get yourself some better samples and vst pluggins, as far as samples are concerned, try looking here, you have to sign up "it's free" but there are alot of people who can help you improve and I think that in a year or two you could be doing some serious sounding stuff.

Keep up the good work, for someone so young it's amazing what some kids are doing these days. Cheers!
