Nice variety of genres in here and solid orchestration. I enjoyed the Main Theme but when Footsteps kicked in I have to say I was really locked in. This is a gorgeous piece and paced expertly - the subtle addition of layers coming in and out as it progresses is really well done.
Inside My World has some really cool textural and ambient stuff going on, also. Kudos on the vocal patches in this - they sound really good and add this whole other layer on top. Well placed vocals are a rarity in jams like this but this was used really well.
Interlude and Mother are both exquisite - soft, progressive tracks that are easy to get lost in. Playing sounds great in both of them, and I'm going to take this opportunity to also shout out the guitar playing (especially so in Bubble Waltz) as it just sits so perfectly in the mix.
The Boss Theme had me curious before listening - wasn't sure what direction you guys would take with it, but it feels like a great sum-of-the-parts. Bigger orchestration, busier melodies and a nice foreboding drive to it to really sell the tone and fit as boss music.
This is a really solid entry all around and I think you guys did really great work, for real. Surprised this has no comments yet - it absolutely deserves more attention. Keep up the great work, and best of luck. :)
