Sounds good to me
I like the feel to this. Sounds more like a tense, chaser scene if anything. Anyway keep it up. I was pretty crappy when i first started, but i got better.
You seem to know which direction you're going in, so after you have a good number of songs, try remixing em when you have an even better understanding of the program you're using. At that point you'll be making beast songs in no time at all.
But for now, keep working toward the one song you aren't testing. And Throw up that soundtrack :)
