Very nice song! Your mix is pretty crispy, which makes it kind of hard to listen to for very long.
I'd tone down the high frequency EQ boosts, and think about bringing some low end into the mix. The bass is there as an instrument, but it isn't really playing that role in the mix. Kick is almost inaudible.
Finally, if you are going to do a sax solo, you should consider using a good quality sax library. Sax is one of the hardest instruments to "fake", so it always sounds obvious when people try it. If it were me, I might use a different instrument instead.
