Menu - Great introduction to the themes. The solo winds all kind of blend with each other, I wonder if you could pan them or adjust what range they play in to have them stand out from each other a bit more (or eq?). Love all the low string passages.
Town - Nice to hear a more mellow town theme. The melodies are rather busy and don't leave much room to rest. As a listener it can be just as exhausting to listen to as it would be to play.
Exploration - Good rhythmic motifs. Similar criticism here. It feels like a track that could use a bit more of one instrument dominating at a time. And room to breathe (those poor brass player's chops!) I like the switching of textures to create interest.
Mystery - Perc. + pizzicato is such a vibe. Good use of more mysterious harmonic techniques too. The delegating of melodic passages was more natural and satisfying here. The cymbal clashes are hilarious.
Battle - Your string writing is pretty good I think, but i feel sorry for the winds! The snare drum was a nice touch, but i wanted more, and even more heavy percussion!
Bad guy - Some very tense string motifs, I like the marcato passages.
