Edit the botanical magazine cover in the first image. Preserve the botanical illustration, dark green paper, cover layout, psychedelic serif lettering style and every smaller cover line exactly as they are. Replace only the large masthead "FIELD NOTES" with "NATURE STUDIES" in the same cream-colored expressive lettering. Change the circular issue badge from "ISSUE 08" to "ISSUE 09". Change "AUTUMN 2026" to "WINTER 2026". All other existing words stay unchanged and legible. Only these three text replacements, no extra lettering, same finished flat magazine cover with all edges visible.

Turn the woodblock print in reference image into a real photograph of a handmade paper diorama: the same composition, the giant wave, the three boats and Mount Fuji, but built from hundreds of layers of hand-cut paper in the same indigo, cream and pale blue tones, with visible paper edges, soft shadows between the layers, tiny paper rowers in the boats and paper foam curls. The diorama sits inside a glass display case on a wooden desk, lit by a warm desk lamp from the left, shallow depth of field, macro photography.
