Fun and great, but you need to add more to this. Firstly, enhance the solo so it is playing throughout the song. It really made an impression on the song as a whole.
Also, add more orchestral instruments, i would suggest Cello and Contrabass the most in the song, give Contrabass pizzicato (which is plucked). Cello would be more legato on this. Also even add some sax's in this, will sound really hot.
And there you go. I suggest at least giving it a shot.
