I hate to say it...
But this sounds like the original with instrument swaps... Nothing more.
You have the right idea but the wrong music theme. It needs more action in it, just having a few fake instruments without drums just doesnt work. It wouldn't work in a FF game.
Sounds like naruto...
This sounds like it would be in Naruto, or maybe, if Naruto and Final Fantasy fused together. I might be able to use this in a movie I'm making (not on NG, a live movie based on Naruto)
It's getting old, just make up your own stuff. This barely even sounded like the battle theme. Horrible work dude.
Please contact me if you would like to use this in a project. We can discuss the details.
