In the first portion with more of the samba vibe, I think the bass is a little loud in the mix. It's commanding a lot of attention and takes away from the horns -- which I think are great and should be accentuated more.
In the second portion, the bass fits in more for me.
Super fun track - a lot going on that rewards multiple listening to sections. The instrumentation all sounds good together - with a slightly different mix and a bit more strategic EQ on the low end, I think you could give each instrument a bit more space
