So Iowa knows how to play the piano somehow it adds a nice gap to her. You'd expect her to have something more bombastic or loud. I'd love to see her closer though that's one classy dress she's got on compared to her regular outfit.
Tuba doesn't seem like it fits Teruzuki that much... But I do like Nagato's choice of instrument. As a cellist myself, I'm quite happy with Yoshinori's work. Why does that bass have six strings?
Just noticed: This is a limited edition metal poster. It went for 1000 yen and any second hand ones are bid up to 8000 yen. The scroll is also fetching the same amount.
So probably won't be seeing the artwork for quite a while, unless they reprint it as a paper poster or in an artbook.
