I think that the three pads, Pad 10, Pad 11 and Pad 21 have ghostly sounds that adds to the Melancholic atmosphere. I think that it works well with the secluded environment. I have decided not to use to sharp of an instrument due to the secluded nature of Titan. The Harp Piano glides through the ghostly pads with a slight contrast. I think each of the instruments work well together. One of my favorites and my favorite on out of this album.
Good work,bro
