This is utterly amazing. That page with of Yuuka and the flowers is one of the most emotion filled piece of art I've ever seen. The parasol, thrown in the air, Yuuka's jubilation, her exuberance, her estactic revelry at the constant screaming of the flowers, the dynamic pose, her horror-turned-joy, the tension flower background it's just amazing.
It's especially juicy when you consider that Yuuka spends most of her time tending to flowers, growing and raising them. Flowers that are terrified of her. Because that's what she does all day, she basks in the flower's terror of her. Fucking amazing.
