On most of the string instruments I know so far including violin, cello, guitar, ukulele, erhu, sanxian and shamisen, if you put them together, you'll see that their strings are in the same pitch order, that is, from their own left to right, their pitches are low to high. But in the Shawzin case, it has the animation of the opposite order: high to low. I'm not sure if there's some string instruments work this way, but if most of the instruments are from low to high, maybe it would be much more intuitive and realistic if Shawzin work this way as well.
And there's another thing I'm thinking about the Shawzin playing: our warframes play the Shawzin by using right hand to pluck and using left hand to press, just like playing the guitar, but when we control warframes, it's using our right hand to press (mouse) and left hand to pluck (1,2,3). I know it may be designed so since it's a mirror, but it still confuse me sometimes.
