Really nice and cohesive work! Your motific ideas were really catchy and i found myself humming along to some of them even if i hadn't had the most time to sit with them, which is a really good sign! I like the consistent instrumentation helping to keep everything together through the sound, as it really helped you feel like everything was the same body of work. As a word of advice, dont be afraid of doing more with your chords rhythm wise! Add in some simple piano arpeggios, or maybe some synth swells to give it movement while staying in your style, it helps keep the song pressing forward and lets the empty space feel more used, and then when you leave room for actual pause it feels even more impactful. Great work overall though! Really like the energy in Mechacanthine Chaos!
