I like both pieces equally well.
Because the piece starts with the piano, and the piano is present throughout the song, It appears to me to be a piano piece with violin and clarinet accompaniment. Yet this piece gives room for the accompanists to add lots of character to the song. In a "live" situation, performance of this, accross several venues, might require hiring local chamber orchestra musicians. As such, it will be performed a little differently, every time.
That doesn't mean performance no. X is better than performance no. Z because a few people like performer X and his/her favorite violin more than performer Z and their favorite instrument. It's all subjective. Now, had this been a violin solo piece, with piano and clarinet accompaniment, the rules (or lack thereof) would be different. I'd expect the violin to play more expressively, as the soloist.
Interpretation of the sheet music will be different between the performing musicians also. So, who's to say what should be changed.
I love the sound of the violin and the music, that's often played on media when portraying a romantic dinner at a quaint resaraunt, and a violinist wandering from table to table setting the mood. But it would change this song, to another genre, or possibly ruin it.
Imagine if Itzhak Perlman, Benny Goodman, and Little Richard competed for the limelight on a song. Utter cacophony on a grand scale for many reasons. Yet they are all great musicians in their own right. This might actually become someone's all time favorite, but not everybody's..
There's a time and place for everything, This is your song, your place, and your time, and therefore deserves merit. I'd take the criticisms of you library choices as motivation to seek choices and as inspiration to continue to improve ,
But had you added a violin and clarinet to a HipHop/Rap song, I'd have a problem with that... :)
