Koto Practice for our new song Taka

We have just started to learn a new song named Taka. I am playing Koto 2 in this song with 6 other people. This is a video of me practicing some parts of the song. I think that the recording did not go as well as I was just normally practicing because I was videoing and it made it kind of hard to concentrate. It is also hard to play a long part at once when videoing because if you make one or two big mistakes towards the end or middle you need to re-start videoing again. I would love to see the difference when we become good at playing this song and this practice video.

I know I am not very good now but I will improve after lots more practice.
