Track 1: This sounds like a track from an old PS2 game I used to play, wish I could remember... Definitely has that creepy-video-game feel. I love a good waltz, and this immediately establishes the theme for the rest of the game.
Track 2: Awesome opening, and great job ramping up the intensity! I can hear the subtle similarities between this track and the first-- somehow they both have that regal, march-ey tinge. I believe it has something to do with these rhythms and the choice of percussion. Good job nailing the subtle details!
Track 3: lovely tone shift here-- this track definitely gives us a cinematic feeling of disaster having struck...
These three tracks tell an amazing story, and have a unique sound that ties them all together. You've done well conveying emotion, good job-- and keep writing!
