Fun fact : I don't know if you're familiar with the Sims 1 soundtrack, but the buy mode 1 music has exactly the same chord progression at the same tonality.
I really like the kind of turnaround you created at 45". And when you put the two saxes together you've harmonically managed to fill the sound space in an elegant way. The music is really very pleasant to listen to.
The negative point is particularly obvious on the piano: lack of dynamics. All the notes are played with the same intensity. You'd gain in human feel with more variations.
I don't know what DAW you're using, but if there's a way to put some randomness into it, it might sound even better.
