Mehh
No points for originality, I'm afraid. D: I think someone commented earlier down saying that they used the same intro melody in a song of theirs? Most likely that's because, if you listen closely, you can hear the same kind of bassline in most of the commercial pop songs on the market.
What I mean by "bassline", by the way, is a set of notes, stretching for a bar or so each, that other notes can stack up on top of to make the melody. You don't actually have to have a bass or whatever playing through for the underlying theme to come through. I'm just sick of hearing this exact one and seeing legions of Newgrounders rating 10s when it's virtually no different to every other techno/dance song on here.
For that reason, I probably wouldn't call this classical, but don't worry too much about that. I made the mistake ages ago of calling a song "classical" simply for including a piano in it.
I'm also not blaming you for using this theme, because it does creep in to the minds of us all when we hear it all the time. I do like looking for something different, though.
But that aside, nothing really stands out to me about this song apart from the occasional distortion and the heavy-as-hell limiting that hurts my head ... I hate how FL Studio loads a limiter into the Master track by default: it doesn't make a nice sound at all; just screws with your levels. Try taking it out and replacing it with a Soft Clipper for a more natural sound that still doesn't become overly loud.
Also, try tweaking the settings on the piano instrument to get more of the sound you want, as well as using the mixer to your advantage. For example, loading a Delay effect in will give it a nice echo.
Sorry if you already know all this, but as you've said you're fairly new to the program, I'm just trying to help. 5/10
