Modern Luxury Gallery Wall Mockup AI Image Prompt

Create an ultra-realistic modern luxury interior gallery wall mockup in a vertical 4:5 composition. Show a smooth matte off-white wall with three large black-framed portrait photographs arranged horizontally in a perfectly even row, with equal spacing and matching frame sizes. Each frame has a thin black border, white matting, and a centered vertical portrait print. The three framed portraits are: left, {argument name="left portrait subject" default="a young Black man facing forward in a patterned blue and gold traditional shirt"}; center, {argument name="center portrait subject" default="a young Black man in a royal blue formal shirt with glasses, looking down while adjusting his cuff, with a pocket square and wristwatch"}; right, {argument name="right portrait subject" default="a young Black man facing forward in a navy suit, white shirt, blue tie, tie bar, and white pocket square"}. Above the three frames, place one slim horizontal black picture light centered over the gallery, mounted with a small rectangular bracket and casting a warm soft glow on the wall and frames. Include a blurred leafy green plant in the lower left foreground, a dark modern wooden sideboard cabinet in the lower right, a subtle white baseboard along the bottom wall, and a gray stone or concrete floor. Use soft natural daylight mixed with warm gallery lighting, realistic shadows, premium interior styling, clean symmetry, sharp frame details, shallow foreground blur, and a calm upscale art-gallery atmosphere. No visible text, no watermark, no extra frames, exactly three portraits.
