A little late to the party, but here's my take on the Emperer's New Groove, aka "The Zenith" from the Final Fantasy Brave Exvius OST, Vol. 2.

Climactic Conflict

The first half is a rather faithful piano arrangement of the original track, followed by a section of development featuring several of the motifs that appear throughout the piece, like the octave jumps, the notable descending scale, the "crystal" arpeggio, the rhythmic pattern of the bass from the opening segment, etc. The piece then recapitulates with slight variations.
