Listening on headphones, first thing I noticed was this song is very left-side heavy, especially at the start. The repeated low note was loud compared to the rest of the mix. Good tension in the tremolo strings at 1:00, though I felt it could've crescendoed a bit more into the glass break sound (maybe pair it with a cymbal crash to make the final moment more impactful, and maybe some reverb). Really enjoyed the drumkit from 0:30 to 1:00. Overall the song is quite creepy and fits the evil twin theme well.
