I like the samples, but something feels off about the mix, maybe too much compression? For the chill/downtempo effect, a quieter piano with more reverb would have suited the track a lot better as well as giving some breathing room for the drum track. Some might prefer a slower tempo though I tend to prefer rapping over faster beats anyway.
One or two more samples for a bridge or just some kind of variation would have also been nice - as it is now, the loop drones on for the entire track.
