Hello Yuki,
I'm surprised you play a nylon string . I studied that thing for years. Do you know Kazuhito Yamashita? If not look him up. The CG repertoire is amazing. I enjoyed your production and it gave a tear to my eye. The child like drawings are perfect for your song . Only crit is maybe have more edits...like zooming in on your face towards the end, stuff like that. This is a good one.
