Nice start! You may be on to something here.
I like where you are going with this, and I think you may have some classical potential (I know you've got the whole Trance/Dance thing more or less in the bag). This piece is particular interesting in that the production value is so good for a first classical submission. Usually the artists get better at writing before they realize that straight-midi strings really don't sound all that hot.
So, I'll throw some suggestions at you now. First, very nice sounds. Good production value there. The piano was a little goofy, not sure if you wanted it that fluffy, but overall it was well mixed, and the verb covered up the strings enough to pass fairly well. You could alter the velocity of some of the midi instruments a little to make it closer to a live performance, but there are all sorts of little tips and tricks that you'll figure out, I could spend all day describing them.
Everything follows the chord progression fairly well, and it is pleasing to listen to, which is more than half the battle. You don't have a definitive melody though. You have an alberti-bass-like figure in the guitar/bass, but that really serves as accompaniment, and you almost have a melodic line on accented beats later on in the song. I would suggest starting with a melody and building everything around that. It can be hard to do things the other way around.
In summary, it is pleasant, peaceful, and enjoyable to listen to. You could stand to work on a few things, but hey, this is a nice piece all by itself. I suppose I could have said more, but all of these things are really up to you to decide. Do whatever sounds good to you, it's your music. I would not have reviewed this if I had not thoroughly enjoyed it, and thought that you have potential. If you've got any questions, hit me up.
