Joyful 5th Birthday Outdoor Portrait of Little Girl Beside Tree Trunk Prompt

Detected Framing & Dimensions: Vertical portrait orientation (approx. 1:1.37 / ~3:4 aspect ratio), full-length outdoor portrait framing of a smiling little girl positioned in the center-left, peeking from behind a vertical brown tree trunk that anchors the center-right of the frame, with a large decorative floral unicorn number "5" prop standing at the base of the tree. The composition preserves the high vertical headroom filled with lush, sunlit green tree canopy and leaves above, soft-focus vibrant pink bougainvillea/flower bushes in the background left, rich green lawn grass filling the entire foreground, and ground clearance below the base of the prop and her feet.
8K ultra-realistic portrait photograph in the same aspect ratio and framing as the uploaded reference: An adorable, radiant young South Asian little girl (around 5 years old) celebrating her fifth birthday in an enchanting, sunlit outdoor garden photoshoot. She stands in the center-left of the frame, playfully peeking out from behind a slender, textured brown tree trunk. She tilts her head slightly with a beaming, joyful open smile, bright twinkling dark brown eyes, soft rosy cheeks, and charming facial features. Her long, glossy dark brown-to-black hair is styled in soft, bouncy curls cascading past her shoulders, crowned with a colorful, delicate beaded headband featuring pastel round beads across the top of her hair.
She is dressed in a whimsical, fairy-tale pastel birthday gown: an airy sleeveless dress featuring a soft canary-yellow bodice with a delicate sheer organza/tulle illusion neckline, fluttery sheer ruffled cap sleeves, and a cascading multi-layered pastel yellow and off-white tulle skirt that falls gracefully to her ankles. The neckline, flutter sleeves, and the scalloped lower hem of the dress are densely embellished with delicate, hand-applied pastel 3D fabric flowers in sweet shades of sky-blue, soft pink, lilac, mint, and pale yellow. On her feet are clean, dainty white closed-toe shoes peeking out above the grass.
Standing securely upright on the grass directly at the base of the tree trunk in the lower right foreground is a large, ornate white wooden/cardboard 3D number "5" prop. The decorative number is styled with whimsical unicorn features: topped with a spiraled white unicorn horn, golden unicorn ears, and a crown of vibrant paper craft flowers in sky-blue, bright pink, and golden-yellow, accented with delicate painted black sleeping eyelash eyes and blushing cheeks along its curved front surface.
The setting is an idyllic, sun-drenched botanical garden or park lawn. The foreground and floor plane are blanketed in vibrant, freshly cut natural green lawn grass. Directly behind the girl rises the authentic, rough-grooved bark of the tree trunk, crowned by lush green leafy foliage hanging overhead. In the creamy telephoto bokeh background (shallow depth of field), radiant patches of bright magenta-pink blooming flowers and sun-dappled green trees glow under soft, warm natural daytime sunlight. Diffused, dreamy natural illumination wraps gently around her, rendering ultra-fine authentic child skin texture, soft flyaway hair strands, translucent tulle fabric folds, crisp flower petals, and gentle contact shadows on the turf, strictly preserving the original 3:4 vertical composition, subject scale, headroom, and cheerful celebration aesthetic.
