I think ts2's texture or object's detaile is the best.
(I myself play violin so I know how ts2's violine is just realistic)

(edit:but ts4's animation of playing violin is the best. I guess anyone who made ts2's animation had no idea about how people play violin, I won't say anything about ts3, cuz it just ' cut and paste' of ts2's animations -_-)
