Ooh this is nice bro. The groove is on-point, and the piano sounds nice. I was iffy on the hats for a second, but I think they take up space (when you use the louder ones), which is nice for a sparse beat like this. I think the intro runs a little long, but thats just me. I do like the way you ended it though. Good job!
Nice sample, but the mixing needs a lot of work. Drums needs to be way harder. Fix the mix and it will be good.
