I've got to say, this tempo is perfect - always felt Bom-Omb Battlefield should be played this fast, and you've nailed that part.
This stands out as a spectacular arrangement - yet as you've pointed out it's the remix department which needs a good revisit.
Look at the beginning of your track, that usually shapes the flow of the rest of the piece - if you can think of an original beginning and then slowly weave this great source re-arrangement in and out - that'd make a great transition, leading into a proper remix.
