This track reminds me a little bit of the late Art Porter Jr., a smooth jazz sax player who died in a boating accident in 1996. I loved his music (his dad was a well known piano player).
In your track I think the mallet lead takes it out of tv usability, and the soprano is a little loud in the mix. There are also some intonation issues on the unisons when you double the melody. I know a couple of libraries that would reject this based just on that.
This will all come down to what the screeners deem as "emotional cocktail."
