(I write these as I listen!)
1 - WOW! The water samples are my favorite. So much all around creativity here. It really starts feeling dramatic. Quite an emotional roller coaster. A very very strong start.
2 - Very very mysterious intro. Quite dramatic as well. Beautiful :)
3 - A joyful intro! So many little textures all over the place! Beautiful and ambient. Absolutely impressive.
I have nothing I'd add to these tracks. They are seriously impressive on their own. This is a very beautiful soundtrack. Guaranteed top 20.. ;)
