the fact that it's all samples *kind of* takes away from its vibe a bit, but I do like the way the drums are arranged and mixed. Definitely needs some bass though.
pt 1 - defo need to hear more bass in this. trying making bass with the heis or pulv. the hat pitching also so seems very random and could use some work. if u want to do pitching in ur lofi beats, just lay down a lil 1/8 pattern with some rolls, and pitch the rolls. :)
the mixing could defo use work too. the hats are louder than everything else where as they should be somewhere in the back in this case. also, work with creating ur own melodies, or chopping samples!
