アゲハチョウ · ペン画と淡彩

Delicate watercolor illustration of several swallowtail butterflies fluttering together through the warm summer air, with fine pen-and-ink outlines over light watercolor washes. Visible cold-press paper grain, soft wet-on-wet blooms, loose expressive brushwork and luminous white space. No text, no signature, no watermark. Vertical 4:5.
