Brilliant job here man, I definitely have some things to say about this one.
-I love the tone of your guitar, it fits perfectly. Both the orchestra and the guitar are integrated very well which I find is usually the hardest thing to do in symphonic metal-ish type songs.
-The integration of the guitar in general, like the placement of the riffs and chords and all that were perfect.
-The drums were very good as well, very intense and authentic sounding. And for some reason I really liked how you used the inverted cymbals.
-I loved your lil' remix of the victory theme at the end. And I'm not sure if you meant to do this, but I liked how you kinda slowed down the victory theme and kinda added a slow, epic flourish to it at 2:33.
-I just have to say this again, the balance you've achieved in this song is amazing. The orchestra, guitar, and drums just fit perfectly and none are overpowering the other.
-It'd be nice of the orchestra sounded a bit more authentic but I'm pretty sure you used the original game track so it's fine.
All in all, great song here man. I'm really lookin' forward to future FF metal remixes. I'm also a big fan of symphonic metal so I was wondering if you ever thought about making any original epic symphonic metal pieces yourself. 5/5, peace.
