This. Is. SICK. I love the drums. As Petitjos said, where abouts did you sample them from? I need them in my life.

The reverby/surreal piano thing in the intro feels a little bit grainy. I'd tone it down a little and push it a bit further back in the mix. The sub bass during the rap feels a little overpowering as well. Overall, with this style, it feels you should just not push everything through so heavy. It has an awesome laid back and chilled feel and I think you should emanate that in your mix
