Many things need much work.
First of all, I am completely baffled as to why you thought this was fit to go into the Classical section. I am not trying to be a category whore or some Aristotelian prick, but come on. You should know what classical music sounds like in comparison to your own music. But that is minor (in many cases I would call Frank Zappa classical) compared to the larger things.
First off, this is about a 10 second loop, maybe less. I didn't bother to count. You stretched a ten second loop over 2 minutes. That is a load of crap, frankly. I am sorry if that sounds harsh, but that is the truth of the matter. There is nothing wrong with repetition; several of my own songs are rife and entirely based on repetition. But the difference in that is that you can't repeat the same thing over and over again, but rather, you need to expound upon the musical idea so people can follow your thought pattern. Because as it stands, this is entirely forgettable. The only meritable thing to say here is that the sound quality wasn't that bad.
I know there is the whole "That is not what I was going for" thing you can play, but then, if it is a simple loop, then why is the loop over two minutes? With that length, you make someone think that something is going to happen during the song, but it doesn't. If this track was 30 seconds long, or 40, tops, the score would not be as bad. Probably a 4. But I personally feel that doing something like that is pretty not-cool. You say "nothing fancy like chorus or crap", but really, adding ANY changes could have made this loop 50x better than what it is. "Nothing fancy" is not how I'd put it. I would put it "something that makes this thing musically coherent". You can achieve a much better effect of "dark and lonely" without a short loop repeated ad infinitum, a much better effect in that people connect to your song.
I am sorry, as I was not "gentle" as you wished. But posting audio is a lot like posting flash. You have to put some actual effort in to it, and it can't be some half-assed stuff done in your program and then sent to a public place, hoping for praise. Don't settle for mediocrity, or below that.
