I enjoyed the beat...although I'm not sure I'd call it R&B, it sounds like a trap remix of an R&B song almost haha. That being said I like that pluck melody and the background countermelody, as well as the drum pattern. the 808s are little too clean for my liking, but that's a huge preference thing. My critique would be the beat could use a bit more melodic instrumentation, but otherwise I like what you got man good stuff
