Let me know what you think please. I really don't know if I'm getting the structures right but I think this is 180 bpm double time it has a 8 bar hook and 16 bar verse or something like that.
I don't listen to Trap but this sounds well produced and well mixed too. Everything works well and sounds together. Structure seems fine to me and its setup for raps over the top.
like @Wesbeats said the kick could hit a bit harder and that 808 a little softer, real nice composition and arrangement IMO, stays interesting and I like the dark atmosphere.
