A photorealistic photograph of a still life, vertical portrait orientation, 3:4 aspect ratio (noticeably taller than wide). Shot on a medium-format camera with soft, even, diffuse daylight. Subject: exactly fifteen real sunflowers arranged in a simple round earthenware vase. Composition, follow precisely: - The vase sits slightly below center, resting on a plain table surface. - The table surface meets the back wall about one third up from the bottom of the frame. - The background wall is a flat, PALE yellow — soft and light, almost cream-yellow, NOT a deep orange or saturated ochre. No pattern, no window, no other objects. - The vase is glazed earthenware, divided by a single horizontal line across its middle: the upper half is pale cream, the lower half is a warmer tan-brown. - The bouquet fills the upper two thirds of the frame in a broad, slightly ragged fan shape, wider than the vase, reaching nearly to the top edge. The fifteen flowers must show a full range of life stages, spread throughout the arrangement rather than grouped: - Four in full bloom, facing the camera, bright golden-yellow petals fully open. - Three in full bloom seen from the side or three-quarter angle. - Four past their peak, petals drooping, curling and browning at the tips. - Four spent seed heads with almost no petals left, showing large dark brown textured centers and green spiky bracts. Style: real botanical photography. Sharp focus across the flower heads, natural petal texture, fine hairs visible on the thick green stems, subtle imperfections and blemishes on the older petals. Warm but light color palette of yellows, creams, ochres, greens and browns. Absolutely no text, no signature, no picture frame, no canvas weave, no visible brushstrokes, no painterly or impasto effect. This must read as a photograph of real flowers, not as a painting or a painting reproduction.

| Tier B — Countable (50 pts) · you count, readers can verify | |||
| Total flower count = 15
Count every distinct flower head. Full = exactly 15. Partial = within 2. Fail = off by 3+. |
15 | ||
| Life-stage mix present (bloom / fading / spent seed head)
All three stages clearly represented = full. Two stages = partial. One = fail. |
10 | ||
| Two-tone vase with horizontal division
Pale upper half, darker lower half, single clean dividing line. |
10 | ||
| Background is flat PALE yellow (not deep ochre)
Eyedrop the wall. Light cream-yellow = full. Mid ochre = partial. Orange/brown = fail. |
8 | ||
| Horizon line ≈ one third up from bottom
Where table meets wall. Within 10% of the one-third mark = full. |

| Tier C — Subjective (20 pts) · capped so taste can't decide the winner | |||
| Photorealism (reads as a photo, not a painting)
Petal texture, stem hairs, believable depth of field, no impasto or brushstroke artifacts. |

| Compositional echo of the original
Does the silhouette and fan-shaped spread evoke the painting's arrangement? |
