Ambient? This seems less ambient than some of your other songs, actually, rather than being the most ambient. I suppose it has less percussion than some of your other songs, which would make it more ambient, but...
Ok, the first thing that struck me was how in the first minute, it really has a soundwash that overwhelms.
Let's see now... normal sectioned review? I think so.
THE GOOD (also the short section where I say what I like quickly):
-Amazing ambient percussion.
-Amazing background soundwash.
-Nice tune and melodic ideas. Particularly beautiful background melodies here for me: 1:37-1:36.
-Nice idea with the distorted pad towards the end.
-Cool pluck-like effect at about 1:17 and in one other area that I can't be bothered to find the time of right now, since I'm a bit pressed for time. But the message gets through, hopefully.
THE NOT-AS-GOOD-WHICH-I-THINK-COULD-PROBA BLY-BE-IMPROVED-AND-HERES-HOW (Also the-really-long-titled-section-that-I -drone-on-in-frequently):
-I noticed a bit of a mixing issue with the kick drum that's somewhat reversed (I assume you used WaveTravlr - I think that's the name of it xD). I'd guess that it's a bit too quick of a low frequency - it cuts out some of the other frequencies for the half-second that it goes. I love the effect of it, but I think there needs to be a little bit more mixing - I'd guess toning down of the low frequency on it a slight bit, checking for some higher frequencies in it might help as well.
-The overall atmosphere of the song doesn't really change overly much. It's really, really pretty, but just goes on and on. I think a break down or a slight tempo change is in order. A chord change would be lovely.
-The cool distorted pad towards the end stops suddenly, and goes into an ending that does seem somewhat uninspired, though it is one of your better ones and certainly isn't bad. I actually like the last strains of the chords, and it definitely works for one of your mainly ambient songs.
Overall, once again - awesome job. Just a few things that could make it better - and the biggest one is more a tip for artist style overall than this song in particular - I'd gotten it myself from my composition teacher a little while ago, glad I can pass it on. :P
G'day, and good luck in the future! Looking forward to more of your work!
