Highway Birthday Billboard

Place the provided advertisement image onto a large Korean expressway (고속도로) billboard. The final image must be a realistic outdoor photograph in vertical 9:16 portrait orientation. ═══ BILLBOARD STRUCTURE ═══ - A massive rectangular advertising billboard dominates the center of the frame, occupying roughly 40-50% of the image width. - The billboard is mounted on two sturdy cylindrical light-gray steel support poles with subtle weathering texture. - Beneath the display panel, there is a visible industrial support grid made of steel I-beams and diagonal cross-bracing. - A vertical maintenance ladder with a protective safety cage is attached to the right pole. - The display panel has a thin metallic frame border around the advertisement. - The billboard is angled very slightly toward the viewer (about 5-10 degrees), giving a natural perspective as seen from the road. ═══ ADVERTISEMENT CONTENT ═══ - The provided reference image must be reproduced EXACTLY on the billboard surface — all text (Korean and English), portraits, illustrations, colors, layout, and design elements must be faithfully preserved with no alterations. - The ad should appear as a high-resolution print on the billboard, with realistic scale and slight surface texture of an outdoor vinyl print. ═══ HIGHWAY & ROAD (LOWER PORTION) ═══ - The bottom-left ~25% of the frame shows a section of multi-lane highway (경부고속도로 style). - Smooth gray asphalt road surface with crisp white lane division markings extending toward the horizon. - A standard Korean highway metal guardrail with periodic vertical posts lines the right side of the road, separating the driving lane from a grassy slope. - A green and white Korean highway distance marker sign (e.g., showing numbers like "63" and "8") is mounted on or near the guardrail area. - One or two silver/white cars are visible in the distance, driving away from the camera on the left lanes, adding a sense of scale and realism. - The camera angle is low, approximately at driver's eye level looking slightly upward at the billboard. ═══ LANDSCAPE & BACKGROUND ═══ - Beyond the highway, dense green deciduous forests cover gently rolling hills in the background. - The scene feels rural or semi-rural, typical of Korean expressway corridors outside major cities. - The forest creates a lush green middle-ground between the road and the sky. ═══ SKY & LIGHTING ═══ - Perfectly clear, deep cerulean blue sky — absolutely NO clouds above the billboard. The sky must be completely clean and cloudless, especially in the upper portion of the frame. - Bright, uniform, natural sunlight suggesting late morning or early afternoon. - The billboard face is evenly lit from the front by sunlight with no harsh shadows, ensuring maximum readability of the advertisement content. - High contrast between the deep blue sky, vibrant green forest, gray asphalt road, and the billboard's content. ═══ PHOTOGRAPHY STYLE ═══ - Photorealistic outdoor photography, shot with a wide-angle lens (approximately 24-35mm equivalent). - Shallow atmospheric haze in the far distance for depth. - Natural color grading — vivid but not oversaturated. - The overall mood is bright, uplifting, and celebratory.
