I wouldn't say it's classical, because it has a guitar in it. I would have put it in ambient. But I guess it's not terribly important.
It's very calming, great when you're stressed. And because it's a loop, you can listen to it for as long as you want without being distracted too much. The looping-ness could be improved, though. Other than that, I'd say it's a well constructed and well performed piece of music. Good job, and it's going in my favorites.
