Great cover
I just enjoyed this piece as it was one of the more relaxing boss battle pieces strangely. I always found it sad when after disc 2 you find out Edea only acted as she did due to sorceress from a different timeline. Really nice cover of the boss theme, nice work on it.
The drums are very nice here and to the theme. The flutes were really pretty sounding yet harsh as well making it sound cool. The bells, xylophone, and trumpets were all quite dynamic and adding to the feel. The ambient violins were also quite well done and give that quality feel as if this is the last battle ever.
Overall, beautiful cover, good times, great boss battles.
