well,
It sounded good. But to me, it sounds like the instruments are clashing a bit. To many and not one style. You have a guitar synthy thing that just doesn't sound good with the other sounds. The victory theme had the square waves trailing, making dissonance.
But, I do like the style you tried to present. This is one of my FAVORITE battle themes from any Final Fantasy, just seeing someone trying to do their own version was nice. Just tweak what your doing and make the sounds "blend" better. : )
