Track 1: The live guitar, and bass combo is excellent! This track immediately feels cozy-- reminds me a lot of the soundtrack to Garden Story, actually! This is an A+ track: you say what you wanna say musically, without any added fluff, and do so in a clearly defined sonic world. It's perfectly done!
Track 2: The addition of more intense drums gives this track a new tone, while the guitar, bass and chiptune tie it in to the last one. Great use of modes here, too. Loved that looser B section-- couldn't quite feel the beat, which was a cool effect actually...
Track 3: Very interesting track... sounds almost like a holiday track from Animal Crossing, wish I could remember which one... definitely love the sparser orchestration.
In all, you achieve great things in a short and sweet way. Top-notch music in a bite-size portion, written with great detail... and of course, major props for recording the guitar! A perfect score in my book. Bravo, and keep writing!
