Track 1: This is a really lovely motif! Beautiful use of mixed meter-- and I love the sound of this cello, so expressive with wonderful legato. Harmonically, I'm interested the whole time. Solid job, and great ending.
Track 2: Ah, this was a refreshing change of pace-- I love the upbeat strings and the layering of new instruments with the second repetition. The B section is well-done, that wooden percussion instrument has such a cool sound to it-- I can't quite tell if it's just a marimba.
Track 3: Another awesome change of pace, this track is so fun! The guitar sounds great too-- and the kit percussion is a wonderful addition. This is a prime example of how to remix an existing melody in a cool way! Despite such wildly different sonic worlds between tracks 2 and 3, the melody helps keep it consistent.
Track 4: I love a nice, delicate winter level theme, and this accomplishes that beautifully. I love the slowed-down melody-- another great way to mix things up, and it opens up room for more interesting countermelodies-- as you have done with the crotales/glock.
Track 5: Another great mood shift, the dramatic piano and drums sound great! For some reason, something about this mix-- maybe the solo violin?-- makes it feel less intense and more computer-ey. I can't pin exactly what it is, sorry.
Track 6: I'm glad to hear the return of that beautiful solo cello! The buildup to the release is really cool-- and the conclusion is wonderful, I love a good bVi bVii I...
In all, I'm impressed by your work. This is a good soundtrack with a lot of character. I think it is missing a sense of identity, which is perhaps a result of just how varied each track sounds. It's a shame, because that variety is my favorite part of the whole thing-- so take my words with a grain of salt. I am impressed-- keep writing, it all sounded great!
