First Attempt
Definitely not bad. Technically speaking, it's all right, and it sounds good. I think as melodies are concerned though, its very hard, at least for me, to latch on to any melody or pattern for the first minute until the background instrument kicks in, so it ends up sounding a bit random. Which could be what you're going for anyway. But if not, I might suggest a very low background instrument here, like a bass, playing something easily distinguished.
I think it's a pretty cool piece.
