it's pretty good
but as far as classical goes, it's lacking quite a lot. It sounds like a techno chord progression that you just put in fl keys, which does not make a classical song. I noticed that it;s a common problem here on newgrounds to think you made a classical song because of a piano.
It got really repetitive, mostly because it was the same chord progression over and over and over. Try adding some new chords progressions to make it more interesting.
But, good job on this song, just work on changing it up a bit.
