I think this does a great job at sounding dark, evil, suspenseful and scary. The pacing and tempo give it this looming feeling, as if something is constantly approaching that you already know is bad. The occasional effects you add (distortion, voices, high strings) give a chill to the song to keep it scary and evil sounding. And the melody changes so slightly that the mood gets maintained, but it definitely gets more and more intense over the 3 minutes. You do amazing work writing orchestral/cinematic/classical, keep up the awesome work!
