Keep the EXACT same woman and face as in the reference image (same identity, ordinary real Russian woman ~50), but restyle her for a joyful birthday celebration. She is dressed up festively to go to a party: an elegant bright colourful blouse or dress (warm jewel tones — teal, berry or coral), nicely styled hair, tasteful festive makeup, maybe small earrings. Big warm genuine happy smile, sparkling cheerful eyes. Bright, warm, sunny celebratory lighting, vibrant saturated colours, golden-hour glow, uplifting festive mood. Still a real, relatable person (not a glamorous model), authentic but radiant and happy. Photoreal, head and shoulders, clean warm softly-lit background, 50mm lens, shallow depth of field, high detail.
