写实3D木质立体字主视觉 AI 提示词

A realistic 3D-rendered wooden typography key visual on a seamless pure white background, with two groups of thick solid wood block letters stacked slightly below center, the upper row arranged horizontally and slightly smaller, the lower row larger and closer to the camera, creating overlap and layering. The wood surface is the key memory point: dark brown and light golden wood tones side by side, with clearly visible growth rings, grain, fine cracks and carved marks, the letter faces coated with a wet varnish that produces concentrated highlights and edge reflections, soft light-to-dark transitions on the sides and bevels. Around the upper letters are scattered curled pale wood shavings, wood chips and a few deep green leaves, the shavings in spiral rolled shapes, the leaves with clear veins and slight sheen, the chips small and naturally distributed. Closest to the lens are the front faces of the lower letters and the shavings at the bottom, the background is clean white with no extra structure, only soft contact shadows under the letters separating subject from white. Lighting is soft multi-light studio setup, main light from above and slightly front, concentrated highlights on the letter faces, short soft shadows, warm overall color temperature, saturated but not harsh wood tones, the green leaves the only cool accent. Centered composition slightly low, letters occupying about two thirds of the middle of the frame, ample white negative space around, eye-level with a slight downward tilt, natural perspective, deep depth of field, all subject in focus. Overall a blend of handcrafted woodwork and commercial product still life, high detail density, sharp wood grain and shaving edges, clean varnish reflections, tidy and uncluttered. In the upper middle of the frame is a horizontal row of large bold 3D wooden letters, heavy weight, tight letter spacing, occupying about two thirds of the frame width. In the lower middle is a larger set of 3D wooden letters, bold, wide strokes, with diamond carved ornaments, occupying about half the frame width.
