Create a female portrait in front of a mirror, with red lipstick writing the phrase “birthday girl 27!”in large letters on the glass, accompanied by small hearts. The woman has long, loose, slightly wavy hair, soft makeup with bold lipstick, and a confident and serene expression. She holds a lipstick and wears sheer black tulle gloves with polka dots that reach her elbows, wearing a black velvet dress with feather details on the chest. Also black, the reflection in the mirror shows her face and part of her body, creating an intimate and artistic atmosphere. The setting is a minimalist bathroom with white tiles and soft lighting with low exposure. Analog photography style, with a retro effect and a red date detail in the lower corner of the image. Elegant atmosphere, fashion magazine aesthetic, realistic and cinematic.

She is wearing a delicate, light-colored (possibly pastel yellow or white) sleeveless dress or top with ruffled shoulder details. On her head, she wears a decorative pastel yellow and yellow floral or beaded tiara, and a small yellow bow clip is subtly placed in her hair above her right ear.
She is holding a small, round, light yellow birthday cake with yellow heart decorations around the base and on top. The cake has the words “I love you” written in black icing on the side. A single yellow birthday candle is lit and stands upright in the center of the cake. On her left hand, she wears a prominent, ornate ring with what appears to be a large yellow stone or several smaller stones arranged in a design.
The background is softly blurred but features light yellow and white checkered patterns, resembling balloons or draped fabric, and several plain light yellow balloons. The lighting is soft and diffused, creating a slightly ethereal glow, possibly from a cool-toned light source, highlighting her features and the cake. The overall mood is sweet, celebratory, and intimate.

Hình 7:
A woman has just turned around to face the camera directly.
She holds a birthday cake with lit number “33” candles in her right hand, while her left hand rests casually on the counter behind her, creating a natural and confident pose.
“Her dark hair is styled in a messy updo with loose, flyaway strands framing her cheeks, adding depth and realism.
She tilts her head gently downward and to her right, giving the portrait a layered dimensionality.””
She is wearing a tight black sleeveless high-neck top, paired with a thin silver ring on the ring finger of her left hand and a simple silver bracelet on her right wrist.
The lighting is natural and warm, with sunlight streaming through a window, softly illuminating the background in cozy golden tones.
In the background, written very large across the mirror, in big red handwritten letters, is the phrase “MY BIRTHDAY” — occupying most of the space, slightly tilted and informal in style.
Below and to the right of Birthday, there is a small filled red heart.
On the left edge of the frame, a small portion of a moss-green door is visible, taking up around 5% of the scene, very subtle.
Her makeup is light and natural — glowing skin, soft rosy blush, neutral eyeshadow, and slightly lengthened lashes.
Her hair is styled loosely, with soft strands around her face, enhancing the warm, authentic atmosphere.
Visual Style (Pinterest / Editorial Aesthetic):
• Warm golden-pink tones
• Sunlight streak crossing the background
• Subtle bokeh and soft film-like grain
• Clean composition with cozy realism
• Harmonious palette: black (outfit), red (text), pink (skin tones), moss green (door)
Composition & Technical Setup:
• Framing: medium shot (cropped at the chest)
• Angle: slightly below eye level for gentle upward perspective
• Ratio: 9:16 vertical
• Resolution: 4K high-quality realism
• Lighting: natural window light with warm highlights
• Style: cinematic editorial photography, Pinterest aesthetic, authentic realism

• You may change the pose, outfit, background, or lighting, but the face, skin tone, and expression must remain completely identical.

A soft pastel birthday-themed portrait captured in a bright studio setting. The overall tone is airy, cheerful, and delicately cinematic, built on a palette of icy white and sky blue. The subject wears a dainty spaghetti-strap dress in white lace patterned with subtle blue floral motifs. The neckline and bodice are structured yet light, evoking a sweet, feminine silhouette. A large satin ribbon in matching baby blue is tied into a bow atop her hair, its tails falling gracefully down her back, adding a playful charm to the look.
The makeup is fresh and youthful — translucent base, soft pink blush across the cheeks, and pale rose-tinted lips with a dewy sheen. The eye area is bright, enhanced only by gentle highlights, maintaining a natural, innocent aura.
In her hand, she holds a small white square cake wrapped with thin pastel-blue ribbons, perfectly complementing the surrounding floating balloons in shades of blue, white, and transparent glassy tones. The composition captures her in a mid-gesture pose — one arm extended forward playfully with a fingertip smudged with frosting, the other hand holding the cake near her shoulder. The overall atmosphere feels light-hearted and cinematic, as though frozen in the fleeting joy of celebration.
Shot with a 50 mm f/1.8 lens for creamy depth and gentle background blur, the lighting is clean, soft, and evenly diffused from a high-key source — creating smooth gradients on the skin and fabric, with no harsh shadows. The image is framed waist-up against a minimalist pale-gray backdrop, maintaining the dreamy, editorial aesthetic of a modern fairytale.
