低多邊形小島裂開，露出寫實的草地與河

Two worlds in one 3:2 landscape poster-cover render, print-safe at the outer edges: polygons on one side, photographs on the other, with a diagonal crack from the lower-left third toward the upper-right third as the break between them. The left side, about 40 percent of the frame, is a low-poly island made from flat-shaded planes, hard polygon edges and stylised faceted trees clustered at lower left. The remaining 60 percent on the right is realistic: a meadow with a river, visible blades of grass, wet river stones, a slight rim of moisture on the leaves, and soft-focus hills in the distance at upper right. Keep the sky at upper centre open as negative space. Lit by one warm key light and a cool fill, which lays gentle rim separation on the forms and crisp shadow contrast where faceted shapes touch organic ones. Along the seam the matte shaded low-poly surfaces turn into subsurface-scattering foliage, reflective water and rough stone. Low-angle wide view, fracture centred left-to-right, foreground details resolving sharply and depth easing off moderately toward the hills. Respect the 3:2 ratio: the diagonal split must stay in frame and nothing important may cross the trimmed edge.
