I have such fond memories of this game, being a Saturn kid and all. I remember only correctly doing the Akuma code ONCE out of probably a thousand tries, so I am very familiar with this theme.
Translating to a guitar-based mix is a great choice, however, there are a number of things you should address regardless of whether or not you would want this as a sub-worthy song:
1) The mix kinda...just...starts. It is actually kind of jolting. Even if you want the rock right in your face immediately, you need to give the listeners a chance to get used to the volume level and somewhat brace for impact. Starting with some flashy drums for a measure or half a measure should do the trick, and allow for the timing of the first guitars to not seem so sudden. It would probably do well considering the original starts with drums, just take that and basically make it more elaborate and rocky then BAM, guitars just happened.
2) The mix sounds too close to the original as of right now. It has pretty much the same feel, except for the guitars and the new section you added. The new section, while nice, needs to be a bit more elaborate.
3) Drums need some major work. There's practically zero transition from section A to section B and back. Furthermore, the sound could be improved with either a new kit or more selective processing on each drum.
4) Is your current arrangement live guitars or sampled? The timing offsets tell me they're live but copiously repeated. If they're live, consider doing multiple takes of the same sections so that things don't sound as static. If they're not live, then I would HIGHLY recommend getting a live guitarist for this.
5) If you want your arrangement to become more sub-worthy, I would think that another original section where you change the basic chord structure would be good, happening after the second B section. Section C, as we'll call it, could act like a bridge and differentiate the arrangement considerably. Right now, I would think your fully fleshed-out arrangement could be something like this:
Intro -> Section A -> Section B -> Section A with solo wankery integrating melodies from various COTA stages -> Section B with solo wankery integrating melodies from various COTA stages -> Section C (Bridge) -> Breakdown and Buildup -> Section A -> Ending
Those solo wankery areas would be a perfect spot to put solos that include integration of other areas of the soundtrack, making things both more original AND more source-referenced at the same time
6) Can't tell with my current headphones but what are you using for bass?
7) We can talk about overall production after your arrangement quirks have been worked out.
Don't be discouraged: I listed a lot that can be improved and changed but you have a solid foundation and picked a great sourcetune. Excited to hear where you can take this.
