okay.. very cool you put this up... I always enjoying hearing fellow TMers.
I like the Getzen's sound ... they can be worked from bright to dark with the same mp.
I think you might be over doing the vibratto. I have to fight putting vibratto in if I hit a note off pitch .. it's a natural reflex to cover up intonation. I also think you find it will make for a more professional sound if you limit it's use and also the intensity of it. Try playing the piece through without any, not for the performance but to see if you find it hard to do. Once you can do that then pick your spots. I like to use it at the end of a phrase on sustained notes ... start the note out without any and then add it in little by little. You can also play with the dynamics .. a good rule of thumb... when the phrase goes up ..increase the volume ... when it goes down .. get softer.
that's my take .. hope that helps
