Thanks a lot for your comment !
I did think of her work for this track, along with Aquatic Ambiance from DKC, Two Tides from Ecco : Tides Of Time, Vangelis' synth sound and Shine On You Crazy Diamond for the guitar part (there might have been a few more I can't remember for now).
Also yeah, ambient sounds is really fun to design, I always try to implement it whenever I can (having experience in games SFX creation/implementation and making musical soundscapes for slower paced adventure games can help when trying to see what kind and quantity of sound works for the kind of experience you want to convey), so anyway, glad that you enjoyed !
