Four-Grid Nail Art for China's Four Major Festivals

Task: Generate a "Four Major Chinese Festivals Nail Art Four-Grid" collage (2x2) Core Instructions Based on a clear close-up photo of a hand (or a reference image of the same style) provided by the user, generate a 2x2 four-grid collage. All four grids must feature the same pair of hands, with identical composition, lighting, and background style, only replacing the nail art design theme. Each grid must have the festival name labeled at the bottom: Spring Festival / Qingming / Dragon Boat / Mid-Autumn (Chinese preferred; English can be used as an alternative if text is prone to errors). Maintain a globally unified style (all four grids must adhere). Composition: Close-up female hand, fingers resting on a soft knitted sweater cuff or light-colored fabric, shallow depth of field, high-definition photography, 4k. Lighting: Indoor soft light (warm light dominant, Qingming can lean towards natural cool soft light), clean background, high-quality bokeh. Nail Art Tone: Commute-friendly, low saturation, translucent and brightening; clean and neat nail edges; embellishments "few but precise"; top coat high-quality without overexposure. Nail Shape: Default medium-length soft square (if the input image has a different nail shape, maintain consistency with the input). Arrangement Rules: Each set clearly defines "main finger(s) (1-2) + accent finger(s) (2-3) + pure base color finger(s) (the rest)", avoid making every finger overly elaborate. Output Layout 2x2 grid collage, neat borders, consistent margins, all four grids of equal size. Add a small title at the bottom of each grid: Spring Festival, Qingming, Dragon Boat, Mid-Autumn (clean, modern font, light weight, uniform position). Four-Grid Design Details (Key: The "custom nail art" for each grid must be specific enough) Grid A (Top Left) 【Spring Festival】 Commute-friendly translucent red and gold accents ("Festive but not tacky") Background bokeh suggestion: Warm yellow lantern light spots + blurred gold ornaments (not overpowering the subject). Nail details: Base color: Milky translucent nude beige (with a hint of jelly-like feel), create a very light "milky translucent gradient" transitioning from the nail base to the tip, overall translucent and brightening. Structure: 3 pure base color nails (with only very faint fine shimmer), 1 micro-French nail, 1 main pattern nail. French tip: Select 1-2 nails for an "ultra-thin gold edge French" (line as thin as a gold wire outline), French curve clean and sharp. Main finger (1 nail, recommended ring or middle finger): Minimalist paper-cut window grille line art (thin lines, ample negative space), the grille occupies only 20%-30% of the nail surface, leaving a large area of translucent base below. Accent materials: Champagne gold fine shimmer even but very faint, like "skin's natural glow". Gold foil only 2-4 tiny fragments, concentrated in a small cluster at the nail base or side, never covering the entire nail. Color control: Red only as a small red dot/short red line (can be a dot in the center of the grille), avoid large areas of pure red. Top coat: Glassy shine, soft highlights, not overexposed. Grid B (Top Right) 【Qingming】 Misty minimalist grey-green translucent ("Quiet, clean, with a misty feel") Background bokeh suggestion: Misty grey-green tones + hazy bokeh with light rain sparkles. Nail details: Base color: Cool grey translucent pink or misty grey-green translucent (choose one, recommend the more commute-friendly cool grey translucent pink), overall leaning towards "misty translucent". Structure: 4 pure base color nails + 1 nail with minimalist line art (very restrained). Main finger (1 nail, recommended ring finger): Willow leaf line: One extremely thin line gently extending from the nail base to the mid-section, add 1-2 short "willow leaf" strokes nearby, mainly negative space. Add 2-3 raindrop sparkles (tiny dot highlights) near the willow leaf, like fine rain falling on the nail surface. Materials: Only pearl or extremely fine shimmer allowed ("almost invisible but light-transmitting" type), no gold foil, no large glitter. Light effect: Satin finish (a softer, more sophisticated shine than glassy, avoiding plastic-like reflection). Texture control: Overall low contrast, clean, no obvious texture layering. Grid C (Bottom Left) 【Dragon Boat】 Mugwort green theme with rice leaf texture ("Subtle herbal scent, details worth a closer look") Background bokeh suggestion: Mugwort greenery + blurred bamboo leaves/scented sachets. Nail details: Base color: Milky translucent nude beige or cool-toned translucent white base (more brightening), overall translucent. Structure: 2 theme nails + 3 translucent base color nails. Theme nail ① (1 nail, recommended ring finger): Minimalist rice leaf texture Use a very faint mugwort green to create a "line embossed feel", only draw 2-3 diagonal leaf vein lines, like "faintly visible" leaf patterns. Theme nail ② (1 nail, recommended middle or index finger): Ultra-thin gold line wrapping around like a binding string At the mid-section or near the tip of the nail, draw a circle of ultra-thin gold line (not thick gold strips), like the imagery of a rice dumpling binding string knot. Accent materials: Fine shimmer only applied as a "thin layer", concentrated from the nail base to the mid-section, avoid the tip being overly glittery and looking cheap. Gold foil still 2-4 small fragments, dotted next to the gold line or on one side of the nail base, enhancing the "handcrafted texture". Color control: Mugwort green only occupies a small amount (lines/small areas), avoid entire nail in dark green. Light effect: Glassy shine (but highlights should be soft). Grid D (Bottom Right) 【Mid-Autumn】 Moonlight milky translucent osmanthus gold ("Moonlight feel, gentle and sophisticated, very photogenic") Background bokeh suggestion: Warm yellow moonlight/lantern light spots + scattered golden osmanthus bokeh dots. Nail details: Base color: Milky translucent off-white or milky translucent nude beige, create a slight "moonlight gradient" – more milky translucent at the base, clearer and brighter at the tip, clean and brightening. Structure: 1 moon phase main nail + 1 osmanthus accent nail + the rest translucent fine shimmer base color nails. Moon phase main finger (1 nail, recommended ring finger): Thin line moon phase (choose 1-2 from crescent/half-moon/small full moon, not a row of nine-grid style), lines very thin, ample negative space. Osmanthus accent finger (1 nail, recommended middle finger): Osmanthus gold dots: Use extremely small gold dots to create 5-8 "scattered osmanthus dots", low density, natural distribution, like falling on the nail surface. Materials: Champagne gold fine shimmer + a small amount of gold foil (leaning more towards "moonlight gold"), avoid silver shimmer stealing the show. Light effect: Glassy shine, overall gentle but clear, close-up details clean.
