I already wrote a pop song. Never heard of Unchained Melody?
Also, I have learned to compose. In fact, I was bestowed the honor of a scholarship to go and study with Anton Weprik and Victor Biely at the Conservatory of Moscow.
I may have exaggerated (which isn't all too unthinkable considering the aggression prominent in your initial reply!), but I remain convinced your piece is a bit of a mess. Try to write something that actually tries to tell the listener a story, or perhaps just whispers a feeling, a general sentiment in the listener's ear. Begin your piece by thinking of a sentiment! I've listened to some of your other stuff, though, and considering your lack of further musical education, I think you're a highly talented composer. You're just ... trying to write using vocabulary you don't know yet. Don't forget the rules of classical harmony. They may seem rigid, but they're pretty worthwhile. Try to form your own idea of harmony using those rules, form your own vocabulary, expand it.
My typical cue is a fairly complex canvas (if I may say so myself) consisting of various layers of 'musical paint'. What you hear (and lovingly describe as a knocked-over bottle of ink on score paper), is the refined variation of prominence of said layers, which is far from arbitrary. Some people, however, have trouble at first to distill what I'm trying to say, musically, and loose themselves in the complexity of my writing, being overwhelmed by all its little details, which I do understand.
