Strange blend of emotions
I like the groove. It's odd however, because it gives me this sense of suspense but with a blend of happy/jumpiness which doesn't really make sense, thus making me emotionally confused (haha, I should get myself visited by a psychiatrist ^_^).
0:40 - strange trumpet staccato. It sounded like some mambo was going to randomly come up next (Oh Chihuahua, anyone?)
Now things start getting more like the original with a "mysterious confrontation" kind of sound, but that tambourine is honestly getting on my nerves. It sounds too loud.
2:12- the trumpets are okayish, but perhaps too bright. This isn't your fault, really... as I said before, it's hard to get nice sounding brass instruments in plugin form.
2:39 - I really like the way you developed the flute. Really soothing and that tambourine fits VERY well in there. This part is awesome. It has some hints of the original, but it's totally different in terms of mood, which makes this an interesting section of the remix, imo.
3:15 - not much to add here. It's pretty much the same stuff as before. Odd ending.
In conclusion, it's hard to explain. I'm actually liking the tambourine, but it doesn't seem to fit all the time and it seems to stick out too much, almost distracting you from the rest. Plus, I think I understood what was "standing out" so much in the general feel of your song. The timbre of the instruments you chose seemed too happy. They don't seem to fit with the general minor key of the song.
Anyway, nice job at managing to grasp the "overall" feel of the song. I tend to suck at imitating original soundtracks so I tend to stick with my ideas (which don't sound nearly as structurally polished as yours), so good job once more. Just be careful with the overall feel.
