First off, I did enjoy it. FFVIII has a beautiful track. Despite its oddities the source is great, though I wouldn't have envisioned it as metal
I won't go into great details with things but what I will say is everything sounds a bit muffled. EQ is the biggest thing I think that could be done to get the production values up a bit. The panning seems rather narrow, it feels like there needs to be more space. Some more reverb, or a different type of reverb should liven things up a bit.
Some of the samples could do with an upgrade aswell, like the opening. Having said that, you could give it a bit more vibrancy to existing instruments with some effects and EQ.
The rhythm guitars especially could do with some attention. Perhaps re-record them just to get a bit of a clearer/sharper tone or ease off on the filtering. It seems as though they're causing the track to sound muffled.
If you're up to it, that opening scale/motif would sound fantastic on guitar, but an equally awesome synth would make that part jump out and grab more attention. In regards to the drums, they seem great, but need more presence in the mix. They could do with being brought out a bit more. I don't think its so much volume that needs to applied, more refinement with some compression, EQ and slightly wider panning on the cymbals.
With regard to the arrangement, I think you could do a little more with it in terms of instrumentation to fill out the space.
I hope that the feedback is of help and look forward to seeing what you do with the track.
