Create a premium 4K portrait lock-screen wallpaper for iPhone using a 9:16 target production canvas of 2160 × 3840 px. Preserve the source image’s visual DNA: one solitary mature tree standing on a gently curved grassy hill beneath a vast star-filled night sky, rendered in elegant monochrome black, charcoal, graphite, silver-gray, and crisp starlight white. Use an AMOLED-dark cinematic nature direction with meditative minimalism, refined high-contrast black-and-white photography, subtle atmospheric depth, delicate grass texture, clean tree silhouette, restrained moonless illumination, and individually resolved stars without artificial glow.
Compose the scene vertically with the tree centered in the lower-middle area, fully visible from canopy to trunk, while the hill occupies the lower quarter and the expansive sky creates strong negative space. Keep the upper clock and widget zone calm, dark, and readable; distribute stars naturally without placing the brightest clusters directly behind the clock. Maintain clear space around the top status area, screen edges, and lower gesture zone. Use smooth deep blacks, controlled silver highlights, clean shadow separation, soft tonal gradients, fine photographic detail, and a tranquil sense of isolation and cosmic scale. Preserve crop safety for iPhone display adjustment, keeping the tree and hill comfortably inside the central safe region. Deliver a sharp, seamless, high-resolution vertical wallpaper with refined OLED-friendly contrast and no visible compression.
Avoid: desktop or landscape framing, ultrawide composition, bright clock-zone clutter, oversized stars behind the clock, excessive star density, constellations forming symbols, galaxies, colorful nebulae, moon, planets, aurora, buildings, people, animals, extra trees, cropped canopy, cropped trunk, distorted branches, tilted horizon, harsh white clipping, crushed muddy shadows, gray-black noise, banding, excessive sharpening, artificial HDR, neon bloom, lens flare, text, typography, logos, watermarks, signatures, UI elements, phone mockups, borders, low-resolution grass, repeated textures, compression artifacts, and important details hidden beneath the clock, widgets, screen edges, dock, or gesture area.
