Scene: A 16:9 fantasy game UI shows a cloaked wizard standing on a glowing circular platform before a large crystal equipment wheel. Faceted blue crystals ring the interface around a bright pink crystal at the center, with violet mist and stone architecture behind. Lock the wizard silhouette, wheel geometry, selected crystal, and lighting for an equipment-switch frame. No readable words, logos, invented stats, or watermark. Composition and rendering: Deliver one 16:9 game-interface keyframe. Separate the character, held equipment and HUD into clear depth layers; keep slot spacing and icon scale consistent, with the selected item visually dominant. Preserve the scene-specific game art style. Let material edges catch the existing light without letting interface glow obscure the silhouette. Keep all equipment fully inside the frame. Avoid: warped perspective, malformed anatomy, merged objects, inconsistent shadows, excessive sharpening and watermarks. Follow the scene-specific text and branding restrictions above.

Scene: An indoor ice-hockey broadcast frame catches an orange-uniform skater driving toward the goal while a goalie guards the blue crease. Show the rink boards, arena haze, ice reflections, and a blank blue panel without readable text. Keep puck direction, player spacing, camera angle, and goal geometry coherent; no real teams, athletes, logos, or watermark. Composition and rendering: Deliver one 16:9 broadcast still at the decisive instant. Use coherent perspective for the playing surface and equipment, readable separation between competitors, and a softer crowd behind the action. Keep the principal subject sharp, with directional blur limited to fast extremities and spray. Preserve the specified broadcast angle and reserve overlay areas clear of the action. Avoid: warped perspective, malformed anatomy, merged objects, inconsistent shadows, excessive sharpening and watermarks. Follow the scene-specific text and branding restrictions above.

Scene: A black game controller floats above a dark angular pedestal in a blue-and-violet studio. Soft rim lights define its grips, directional pad, sticks, and buttons while the background remains free for copy. Preserve the controller geometry, centered perspective, highlights, and pedestal edges. No readable branding, extra products, hands, or watermark. Composition and rendering: Deliver one 16:9 commercial product still. Keep the complete product silhouette inside generous crop-safe margins. Resolve edges, seams and material transitions precisely; shape highlights to describe volume without clipping bright surfaces or crushing dark details. Align reflections with the object and light source. Retain the stated camera angle and existing negative space; add no decorative props. Avoid: warped perspective, malformed anatomy, merged objects, inconsistent shadows, excessive sharpening and watermarks. Follow the scene-specific text and branding restrictions above.

Scene: Inside a glass mountain cable-car station, an older man in a dark coat reaches toward a woman as they meet on an icy platform. Snowy peaks, cables, and gondolas fill the background through the windows. Hold both figures' eye lines, walking direction, cold daylight, and wide spatial blocking for a cinematic storyboard. No readable signs, logos, or watermark. Composition and rendering: Deliver one 16:9 storyboard keyframe, not a collage or an action sequence. Separate foreground, character plane and background through the existing light and atmospheric depth. Keep the stated pose and eyelines readable, and retain environmental landmarks for continuity. Match the described photographic, illustrated or puppet medium; give fabric and surfaces texture appropriate to that medium. Avoid: warped perspective, malformed anatomy, merged objects, inconsistent shadows, excessive sharpening and watermarks. Follow the scene-specific text and branding restrictions above.

Scene: In a bright tiled bathroom, a wet shaggy dog bounds forward as a mint towel, soap bubbles, and water droplets fly around it; a surprised groomer in an apron reacts behind. Freeze the safe splash moment with believable arcs, clean separation of dog and person, and soft daylight. No injury, readable text, logos, or watermark. Composition and rendering: Deliver one 16:9 physical-comedy still at the described instant. Make the cause of the gag readable through body balance, grip and object spacing. Separate the reaction from the airborne props; retain believable gravity and contact points. Keep the face and important props sharp, with only restrained directional blur on fast edges. Preserve the stated lighting and room or stage layout. Avoid: warped perspective, malformed anatomy, merged objects, inconsistent shadows, excessive sharpening and watermarks. Follow the scene-specific text and branding restrictions above.

Scene: A sepia archival scene shows a camel caravan resting beside a small oasis, with travelers in wrapped period clothing, baskets, palms, and rocky desert hills. Restore the old paper grain, camel tack, clothing folds, water edge, and stable documentary framing. Do not add modern objects, readable signs, logos, captions, or watermark. Composition and restoration: Deliver one 16:9 archival-style still. Preserve the original framing, period-specific construction and restrained tonal range; retain monochrome, sepia or faded color as described. Recover modest detail in faces, clothing and architecture without synthetic sharpening. Keep fine grain and authentic aging consistent across the frame; repair damage without replacing historical features. Avoid: warped perspective, malformed anatomy, merged objects, inconsistent shadows, excessive sharpening and watermarks. Follow the scene-specific text and branding restrictions above.
