Thanks guys! I do see what you're saying there, Willow. Like Valzi said though, it can be difficult to cram a lot into a 5k with only one sample. I could have used more samples, but I wanted to challenge myself by limiting it to only the one.
Indeed, what Willow is complaining about is also the tune's hook. If you could somehow cram another instrument in with the pan centered (or not as extreme) it could introduce a bit more variety without using a second sample.
