Love the care the authors put on making the most out of the sound fxs. On pages 29-32 you can see Shiori fiddling with the guitar, playing clumsy and increasingly smaller (quieter) notes, then at 32 she plays a bold and straight strum, showing her emotional resolve. It's just like on ch.20 (the drummer training one) you can read how his playing change after getting in the flow for the first time.
