Nice, this is a really different approach to the song - more playful than the original, at first, but as Skyline Drop mentioned, still with a subtly dark atmosphere to it. And the new reggae-style rhythms present the familiar melodies in a new and interesting light (a number of your progressions here have been stuck in my head since I first listened). The eerie choir entering the mix around 1:20, for example, does a good job of maintaining some of that haunting quality the original has - though I'll echo the concerns others have mentioned about the trombone, which is about the only thing that threw me off somewhat. Extra expression/humanization would help but I also think maybe a different, less artificial-sounding sample choice might be needed.
The arrangement and buildups/breakdowns are great too. I like the fierceness of the organ at around 2:28, it serves as a reminder of the song's origins as a theme for a place full of dread and dangerous surprises. Same for the similar reprisal at 4:00, though I'll agree the sudden shift towards a happier tone at the end seems either out of place or needs a better, more gradual transition.
