Tangled Threads: a great opening track, this certainly sets the scene for the dramatic story you've laid out. The unusual rhythm in the synth, while pretty cool, does detract from the piece's atmospheric qualities because of how closely placed it sounds in the listener's ear. Lovely when the strings come in! There's lots of cool synths on display here.
Where Do I Run: Nothing like a IV-III-IV progression to portray melancholy! It's a beautiful opening to the track. This track is able to capture the atmospheric vibe much better for me: the strings still have a unique, pulsing rhythm (similar to the one the synths had in Tangled Threads) but without the harsh attack that pulled away from the other, slower instruments. Loved the entrance of the guitars, and nice drop. When you write a repeating chord progression with instrumentation changes at every repeat, it can become monotonous very quickly; hence why this drop was very important to keep the interest up.
Day By Day: what an exciting harmonic world we open in! While every piece thus far has been totally tonal, this one fully embraces atonality-- and I love it. I would have loved to see more of this sharp, angular, gritty harmony in the earlier pieces. Once the smaller, kit percussion enters around 1:30, this sounds like something I would totally study to-- much more of a chillhop vibe.
In all, I'm impressed by your ability to build up tension in a track-- and the very unique harmonies of Day By Day. Keep writing, and great job!
