Are you looking for advice in a specific area? Since you said this was mostly done, I am assuming you aren't changing much of the track...
Right off the bat, i have two arrangement suggestions - the intro could be a little gentler, no need to rush things, especially when using two or three melodic phrases at once. Also the outro is a little abrupt, especially with all of the drama and big sounds used across the entire track.
While the plucked instrument and sax play each other off well, they could use a little more contrast. Perhaps a little EQ ing to the string would make the sax come alive.
