You captured the sound of the early 2000s Nintendo games so well with this track! I think that the ostinato synth bells over the droning bass/electronic sounds works so well to keep the ambient nature of the track that fits the Metroid Prime composition style so well. The key change at 0:41 definitely felt like a Legend of Zelda moment when it arrived, but I could certainly see this in a Metroid game as well. I think that the chord changes you made were very interesting and drove the piece forward without disrupting the ambient feel. I think you have excellent instrument choices for this both for the credibility of the track and for the general impression overall. Great work and thank you for sharing!
