Mono made a lot of good points.
As is, this is still a pretty conservative track and probably wouldn't be up to OCR's standard in that light. Here are a few things that you could do to start liberating yourself from the original feel to get this to be less conservative:
1) Change up the drums. You can still have the same feel, but having the same pattern almost to a tee makes it hard to think of anything but the original. Drums can make or break a great track as they're often what gives the energy to the song, so making sure you have a fitting beat is very important. Change it up a bit, make it less static.
Change some notes! This could be approached from many angles including adding an original lead somewhere, changing the chordal progression underneath, or something more daring like going from a minor to a major key (usually very hard to pull of well). The synthy lead around 2:35 is a good start in this direction, but work on it some more still. I like the idea but it could be done much better, try adding some modulation/automation to bring it to life a bit more.
Other things that would obviously help out a lot are:
- Real guitars (2:35ish)
- Better drum sounds (Keeping the feel of the originals kick is fine, but layer it with some other sounds to beef it up)
- A better transition from the intro to the first section (:25ish). The stop-and-go thing that is happening now is odd.
- A moving bass line. (I'm listening on work speakers, but I don't hear much in the bass department at all)
Keep at it and don't give up, it's a good start! This is one of my favorites from FF7
