Nice one!
Angsty rock piece complements the theme very well, especially the last part.
Mix is good, it has some place left for vocals (if you'd ever want to make song out of it, it's pretty much ready) or dialogues (if you want to use it as a scoring track). Not sure whether it was on purpose, but the overall sound is a bit retro. In a good way though.
If I were to nitpick, I'd probably say to chill out a bit with the melody (0:33 onwards). It's very nice but a bit "spammy": give our ears a beat or two more to process what we heard.
Solid work overall!
