This is difficult to listen to without moving a little. Some of the horn samples weren't doing it for me, but in other places they sounded pretty good.
I may pull the verb a bit, not sure if it's applied uniformly or if some parts are treated more heavily.
It's cool that you played the bass, this place needs more bass players :-)
The guitar does need to sit better, since there are no vocals, I would bring it down the pipe and spread the horns. And since you played that bass? I would like to hear it a little clearer? Maybe HPF the horns and guitars a bit more?
Not sure what tools you have to enhance the bass, there are a lot of good ones out there.
Good job overall, looking forward to the remix.
