A happy, ocean feel to it.
To me, it felt like it had a nice, happy feel to it, and it gave the impression of someone exploring the wide open ocean, occasionally going in to a couple caves to explore.
It does feel a bit too, I don't know, busy for an ambient track, but hey, that's just your style. I'm the kind of weirdo who listens to drone, so I can't really say that my taste is valid, haha.
Also, some of the transitions from section to section felt a little bit abrupt, but overall, it was worth listening to.
