Liked the loop a lot better. Despite it's length it sounded deeper and fuller than this. You said you had no clue how to extend it. Maybe just play the loop a few times in the middle?
When I listen to this and compare the two, I think, "less intro, more substance."
sorry for bringin' down your score a bit but i just don't like the intro. the rest is amazin', though. very ambient and nice to listen to. downloaded!
