I love how you flipped the sample and the drum programming is good, but I don't really like the lack of effects to make it seem more vintage, and the drums feel a bit too robotic.
a technique I like doing with my drums to make them feel a bit more natural is playing around with the velocities in all the sounds and slightly offsetting them a bit to make it feel like a real person played it on an mpc.

overall good stuff!
