Guiding Light: I love the synth layers and the piano ripples. The simple motif is very intriguing as well and creates a sense of wonder among the minor chord usage. The emerging electric guitar with lots of reverb is a perfect addition to the already fantastic instrumentation.
Surviving: This is my favorite of your 3 tracks. The 3/4 feel with the use of the castanets gives this track a sea-faring vibe for sure and the bass at 0:23 definitely gives a sense of adventure. Your orchestration is phenomenal and so many instruments/layers meld together so well. I also love the repeat of the motif and use of polyrhythms. This is a really awesome track!
The End: This lose stinger is ghostly and dark in a way that conveys a seriousness and finality while still sounding connected to the rest of your OST. Stingers are an important part of video game composition, yet they are an underrated skill to have. I appreciate that you shared one in your OST which definitely adds to your creativity category in my opinion! Thank you so much for sharing!
