It's not too bad, I suppose. I can already tell that it's FL produced (but only because I've been using FL for god knows how long now).
It's pretty repeatitive, so I'd work on making more sections to it. Maybe build it up and make it REALLY big (which is hard to do if you know what you're doing). I think you could also get some use out of the Sytrus stuff on FL.
Not bad, just add more and build it up.
