Sounds awesome Red; Production is very good, and your choice of pads, arps etc added a fresh coat of paint to a pretty awesome classic. If I read your description correctly, you were going for more of a cover right? If so, great job - only a few minor gripes here and there (:48 - When the piano first comes in, VERY minor clash of notes) and being that this mix have been covered a fair amount of times, I feel like you could've expanded on it a bit more (perhaps a piano solo or something of that nature - the source leaves a ton of room for it).
Not trying to be a jerk here, as I know what it feels like to work hard on something then have some dude criticize it - but it's something you may hear from the workshop/judges as great production quality isn't everything.
That said, it's still a very good mix and best of luck either way. You're pretty confident in your abilities, so I personally think that getting accepted here shouldn't be your ONLY driving factor. Have fun with your music and improve while doing so.
Just this wannabes opinion though. Keep at it.
