I'm sort of disappointed you didn't tell me this was FINALLY out, but I'll try not to bias my review :')
Okay so! I absolutely love that flute at the beginning. Yes, both of them. They're so perfect, the way they interact with each other is right on. I really like the swell transition, although personally after that I wouldn't have put in the harp in the background, or at least not the lower pitched one! I think it counter balances too much in the bass area. Or is that the guitar? I'm not sure, but I wouldn't have put a plucked string in there. I'm not sure what though, maybe some air instrument? I dunno!
The melody is just... hmm, how could I describe it? Majestic! That's the one. Everything just works... how do you do this?! D:
The lower part right after with the guitar melody, I always wait out for that one. Every time it's just so chill but it has some sort of energy to it, it's weird! Bagpipes fit great, though I think the mixing could've been a tad more balanced (less bagpipes, more guitar!), but maybe that's just because I love that guitar so much :p!
When you start hitting those glass mallets... wow! I'm running out of adjectives. Melody comes back in a softer, calmer tone. Slower... zen. And then those strings! The waves hitting in the background. The little chimes. I don't think I've heard this much attention to detail from any of your songs before. This is a big "step" forward! (sorry I couldn't help myself -- IT HAD TO HAPPEN OKAY)
All in all, it's great. I do think there are minor flaws but those may just be personal taste. Besides, you've worked on this for so long, you deserve to release. I remember when this was just an early prototype, it has evolved so much! I'm so glad it's arrived at this state. Please make more, this is amazing. You are amazing!
