I'd tweak that tambourine-ish sound. It sounds very light, and in an unconvincing space that doesn't really glue with the rest of the track. I really dig the drop at 1:46.
I think you could make the vox sample from 1:06 - 1:15 into something more musically compelling. It's close, but could be stronger.
That marimba part that starts at 2:16 is cool, but starts to lose me after around 2:26 or so, and then gets a bit irritating. 2:36 - 2:46, I'd totally pull it out.
Cool stuff. Just some thoughts.
