FF7 Piano Collections - Valley of the Fallen Star (6/13)

I feel like this arrangement is more of an original composition than an arrangement. It uses the melody and motifs very well to develop a nice piece, but I don't get that "canyon" feel from this rendition.
I tried a few attempts at making it sound more similar to the original, but none of my attempts felt any better, so I was mostly loyal to the sheet music.
