The brass needs better mixing for sure. A lot of elements for that matter, though it still sounds really good. I'm really not too sure what could be done aside from meticulous sequencing, which you've already put a lot of work into. Maybe that little vocal effect? I'm not really sure why it's needed, it seems to be an obligatory thing that beat makers use because everyone else does it.
Other than that, I think it's really good. Definitely on the right track. Sound balancing and mixing go a long way.
