It sounds interesting at the least, I would enjoy it a lot more if not for 2 things; The first is the lack of change when you bring the melody in, the 4 notes repeated twice that are descending; you could have done so much with that!!! D=
But, the main reason is because you said it sounds like a Mozart song; forgetting my being pedantic about the term "song" instead of "piece", that was the melody from 'Requiem for a Dream', which is constantly mistaken to have been written by him, but it wasn't. It isn't even based on anything he wrote D=
Still, the music itself was decent =) I'm sorry I can't say it really stood out as something I instantly had to download, but I would definitely listen to it again in future!
