Couple Birthday Celebration Photo Prompt

Create a photorealistic full-body portrait of the same couple from the reference photo, standing together behind a birthday table with a chocolate cake, candles and gold balloons in a cozy decorated living room. The girl wears a red midi dress with heels, the boy wears a white shirt with dark jeans and sneakers, both standing still in a grounded pose with feet planted on the floor, hands fully visible with five natural fingers each, one hand each near the cake knife. Render strict correct anatomy with exactly two arms and two hands per person, natural joints, realistic proportions, no motion blur on bodies. Behind them show blurred fairy lights, photo garlands and gift boxes. Light their faces with warm indoor key plus soft fill. Frame head to toe with margin above heads and below feet. Shot on Sony Alpha A7 III with 85mm f/1.8 lens, sharp focus on eyes, natural skin texture, detailed clothing. Finish with warm cheerful tones and subtle film grain. Keep face same as reference for both, not CGI, not illustration. Strictly avoid extra fingers, deformed hands or feet, extra limbs and plastic skin.
