1st beat is a dope sample flip of funking for Jamaica, but I feel like its just the skeleton of the beat. Like it's missing some more sauce.
2nd beat is dope, but you gotta replace that one cheesy sound in the melody. Make it a piano or some type of dark organ and the beat becomes darker and better immediately imo
3rd beat, you pump faking and adding too much shyt to an already dope beat. Get rid of that loud ass light hitting ticker sounding instrument. it clashes with the dope melody you got going on. I love the transitions, but you gotta take that one sound out or replace it with something that doesn't clash so much. beat is dope tho. just give it an intro too.
4th beat, nice lil subtle sample flip for the main melody. beat is nice. wouldn't change anything
overall good shyt breh.
