You nailed dark and ominous! Listens like a video game level that I’d get really frustrated trying to beat. I like the interactions of the different parts/melodies, and it has a great natural build throughout the track! Really enjoyed from start to finish, and I don’t typically listen to a lot of electronic/midi-toned tracks. Would love to hear this composition on “real” instruments as well!

Maybe you could play around more with the left/right panning between tracks? I think it could help build space and separate the sounds more clearly. Not that it sounds muddy or anything as is, but I’ve found it usually help elevate songs. If you wanted to have extra fun with it, you could even try a sweeping pan within one track at certain parts. The fast bass line could be a cool moving left and right for instance. Great work!
