Very unique piece! I myself have just found out about all the gold that is in the LABS stuff, and I'm happy to see how awesome they can sound. Despite your aforementioned lack of theory, it seems to be a pretty solid piece for what limitations you seem to have. Some parts feel like a slight mishmash of things, and somehow I'm getting a bit out of place there (like the marble dropping sound that somehow sticks out for me) but everything else is pretty much in place.
I also appreciate your very detailed description of your techniques used, helps other producers who want to learn something new!
