Photorealistic Luxury Number 3 Birthday Poster

Goal: Create a professional luxury birthday poster in a vertical 3:4 ratio celebrating a young child turning {argument name="age number" default="3"}, with an elegant editorial studio look. Canvas: Portrait 3:4 composition, high resolution, centered layout. The entire frame is a snow white paper wall with subtle fine texture, soft warm daylight, gentle shadows, and a premium minimalist birthday aesthetic. Main subject and layout: A very large number {argument name="age number" default="3"} is precisely carved into the white wall as a deep architectural cutout niche. The number has thick rounded edges, visible depth, realistic inner shadows, bevels, and smooth volumetric paper/plaster details. Inside the hollow number is a muted pale blue gray interior room. A toddler boy sits in the lower middle opening of the number, slightly overlapping the front edge, wearing a plain white short sleeve T shirt and cuffed light blue jeans, barefoot, relaxed pose with one knee raised and one leg hanging down. Keep the child’s face softly anonymized or blurred while maintaining realistic hair, body, clothing, and pose. Decor details: Fill the carved number with exactly 12 visible balloons in a navy blue, powder blue, white, and soft gray palette: 1 navy balloon at the upper left, 1 pale balloon partly hidden behind it, 1 gray balloon near the left interior, 1 white balloon at the upper right, 1 navy balloon at the upper right, 1 powder blue balloon near the right upper middle, 1 white balloon on the right middle, 1 large powder blue balloon in front on the right, 1 navy balloon at the lower left, 1 white balloon at the lower left foreground, 1 small powder blue balloon near the bottom center left, and 1 navy balloon at the lower right near the child. Add exactly 5 white floral arrangements: a bouquet at the upper left interior, a small cluster in the middle left recess, a larger cluster in the lower left opening, a bouquet on the right beside the child, and a small white floral accent near the right lower interior. Use thin balloon strings and realistic botanical detail. Text content: Centered beneath the number, add three lines of elegant serif typography. First line: {argument name="child name" default="SAAD"} in large metallic gold uppercase letters with a subtle 3D sheen. Second line: {argument name="chapter line" default="CHAPTER 28"} in smaller dark navy uppercase serif. Third line: {argument name="birthday tagline" default="365 MORE DAYS OF MIRACLES"} in dark navy uppercase serif, slightly smaller than the second line. Visual style: Luxury birthday poster, realistic 3D paper cut architecture, soft studio lighting, creamy white and blue palette, gentle depth of field, polished premium finish, clean negative space, no clutter, no watermark, no extra text.
