just an fyi, the idea is to go through the mod review process before you submit; the whole point of workshop moderators is to catch problems that can be addressed upfront and provide feedback that will give you a better chance of getting past the judges- as opposed to submitting, spending a matter of several months (or more) for them to get around to it, just to be rejected.
the mixing all-around is pretty flat and muffled. lot's of action in the mids, not so much in the low/high's. a lot of samples used, such as the strings, choir and piano have a very 'fake' quality to them. the orchestral hits sounded super-cheesy, and weren't mixed too well either. edit: i thought the guitar was sequenced for the first few listens, my apologies for thinking so if that's not the case, but the tone and mixing there didn't sit too well with me /edit
one of your high-hats is panned pretty hard left, and is coincidentally also the loudest piece of percussion in your set- the rest of the drums were pretty drowned out for the most part imo, and could probably use a boost to get things more balanced. sections with the choir/piano were also pretty unbalanced, with the guitar and choir being the dominant forces.
a lot of this seems like cover material, moreso than an arrangement. i could break it down a little better if i knew beforehand where each source was taking place in your mix, but from what I've gathered over a few listens, it seems like it could use a bit more interpretation and original writing to vary things up and make it your own.
i don't mean to discourage, but this is quite a ways from making it to OCR and I think you may have jumped the gun with a submission (although the judges will be able to provide you with some helpful feedback when they get around to it).. on the other hand, i'd focus on new material anyway to help expand and sharpen your skills. the musical chops are here, but the production (and probably to a lesser degree, arrangement) needs some practice. good to see that you are active and enjoying the workshop forums, and i hope my feedback is of use! best of luck
