Really good stuff. Definitely get a Danny Elfman vibe. Especially at 1:11 when the pulsing synth kicks in. I love the composition, the track has a good sense of building up throughout. The way you use the samples sounds great, although I would say the one thing worth fiddling with is expression and timing controls on your MIDI. It definitely seems that you've done some of that, but there are just some parts that I can't help but feel sound robotic. There's really only so far you can go with samples though, and I think what you have going on is pretty nicely up there.
