Hahha, yeah. This is not chiptune o.O (jk).
I like it; it's hard not to like something you've done. I already mentioned this, but holy **** you've been productive for a while now. I've got to say I liked the previous composition you posted slightly more than I do this, but I still enjoy it quite a bit.
It's relaxing, and works well as background music. This is just my opinion, but I think it lacks a really 'catchy' melody, but I'd say this song doesn't necessarily need that. Of course there are several melodies, I'm just saying I probably won't remember them tomorrow.
Aside from that, I like the way you put a multitude of instruments (and other sounds) together to form the entirety. I also like the way that the more "heavy" percussion enters at 1:00-1:05.
It's impressive the way you still manage to bring in several different themes (like the shift at 2:41), as well as the fact that they complement eachoter so well.
According to my ears the mixing also seems to be sufficient (at least). However, I'm not to be trusted when it comes to that, as I am very new to mixing at a whole. I'm simply a (starting) hobby musician, so I can't give you any more a credible review than that.
Overall, I loved it; keep up the good stuff ;)
ps. That ending though!
