Minimalist but really damn good
nice ambience - this is fine on it's own but it would be even better if it were used as a lead in instad of a standalone - you know?
I was waiting for the hook - but then, it is ambient after all.
Diversity lower because ... well, becuase it's not incredibly diverse but that's alright. Effort lower in part due to Diversity and also because even though it was good, it could have been "completely bad-ass holy shit" good.
Either way - a 10 overall and a 5 from me.
