Feather Silhouette with Dusk City Sky AI Image Prompt

Create a vertical gallery-grade poster from a source-like everyday scene: a dusk city-sky photograph with deep blue sky, teal-to-cyan gradients, soft orange-pink clouds, black utility pole silhouettes, multiple diagonal power lines, a low bridge or rooftop horizon, and tiny streetlights. Compose the image as a before-and-after poster: the top 30% is a wide rectangular strip showing the original unedited photo, with one tall black utility pole slightly left of center, exactly 5 prominent diagonal power lines crossing the sky from upper left to upper right, a dark horizontal bridge line near the bottom, and warm sunset clouds. The bottom 70% is a clean warm-white gallery background containing one large centered feather silhouette, vertical and slightly curved, filled with the same sky photo textures so the original scene remains visibly embedded inside the feather. The feather must have a dark central quill running from bottom tip to near the top, fine barbs along both sides, delicate cut slits and misaligned sliced gaps, and the same diagonal power lines continuing through the feather interior. Use the photo's strongest visual features only: blue sky gradient, orange cloud patches, black linework from power cables, dark horizon silhouettes, small light spots, and edge flow. Keep the feather abstract and photographic, not a realistic bird feather illustration; avoid plain animal silhouettes, avoid cartoon style, avoid full redraw, avoid extra objects, avoid text, avoid watermark. Overall style: minimalist framed art print, high contrast, subtle film grain, crisp negative space, elegant double-exposure collage. Use {argument name="silhouette subject" default="a single feather"}, {argument name="source scene" default="dusk city sky with utility poles and power lines"}, {argument name="background color" default="warm white"}, {argument name="primary colors" default="deep blue, cyan, teal, orange-pink"}, and {argument name="poster layout" default="top original-photo strip with large transformed silhouette below"}.
