The Herald was a lovely opening! I must know what library you used for the guitar. The cello melody got a bit buried by the other instruments when they all came in. I also felt like there was a lot happening all at once, but it was hard to discern the piano runs from the guitar and the strings-- it was all a bit muddled. Be careful with overloading your tracks!
The Forest Spirits is interesting-- the combination of organic, close-mic flutes and synth flutes was cool in the beginning.
Good use of wave sounds in Seaside Respite, though they did linger for a long time before the piano came in. Beautiful piano improvisation here, it was certainly soothing and reminiscent of the flowing waves.
Gluttonous Miasma had a really cool opening! All of these synth sounds are really epic and help to build the mood! Again, the cello melody here is hard to pick out amidst all the synths. Super innovative use of what I think was coughing sounds? There is a huge variety of timbres at play in all of these tracks, which I think keeps the drone-like harmonies from getting repetitive or feeling too slow.
All you could wish for had a really interesting quality to it! The fuzziness of the piano gave it a homey vibe which aligned with the idea of being in a small house with a star. The intense arpeggios were the only thing that didn't quite work for me in this piece: it was a little too intense for the mood the story implies.
In all, this soundtrack is very well-done--you have a knack for making epic, sweeping tracks, as well as wonderful keyboard skills. I applaud you for using real recordings too-- not an easy feat to make them sound this high-quality!
