A general review
This is a general review for all your classical work (just posting it here because I think this song is one of the best).
I think that the music you have on here is very good. It's not the best I've heard, but you certainly belong up there with the elite composers on NG. Some of the songs could use a bit more variety at times (as in, many of them have a repeating pattern in the background for most of the song). This isn't necessarily a bad thing, but it would make your music even better if you change it every once in a while during the song.
By the way, where did you get your samples from? I don't remember seeing stuff like that in FLStudio. Are they from the extra sample downloads?
