The Speltower: Those chords on the vibraphone make it feel very hypnotic, I felt very immersed in the music when listening to it. Very good work.
One Man's Madness: Has a very nice melody, estructure and chord progressions too. Great boss theme.
Requiem For Angels: Really beautiful music and great use of the leitmotiv, I think it would fit very well the villian you described. Very nice orchestration job as well!
