This is a good example of what can be produced in just the demo of FL. I loved the melodies in there and the relaxation of the song. While listening to it I did think it reminded me of Mirror's Edge's theme song. If you haven't heard it yet you should go listen to it.
Now, for some critique. I don't know how this song sounds on your system and whatever you used to mix it with (speakers, head phones, ect.) but on mine the drums sound a little bit quiet. This seems like a song where when the drums are playing during the main parts of the track they should really be up in your face. That kick especially, otherwise it feels as if the song loses a lot of power.
Another thing is in the beginning. There's a weird overtone going on with the bass that sort of rattles the speakers, and not in a good way. You might want to, if you can, go back and EQ those frequencies that are causing this out. Other then that, I believe this was an excellent and beautiful track.
