Bhai Dooj tilak in a warm family courtyard

Create an original natural photograph of a fictional adult Indian sister and her adult brother celebrating Bhai Dooj in a quiet family courtyard. The sister gently applies a small red tilak to the centre of her brother's forehead with one fingertip. Her brother sits at eye level beside her, smiling naturally; show their faces in a three-quarter view and both hands clearly with plausible anatomy. A small brass thali on a nearby low table holds a bowl of red kumkum, a few rice grains and two pieces of mithai. Clothing: a simple cream-and-maroon sari for the sister and an ivory cotton kurta for the brother, with natural folds and modest everyday jewellery. Setting: a lived-in courtyard with a wooden doorway, a few marigold flowers and softly blurred family decorations. Lighting: gentle late-afternoon side light, warm natural skin tones and soft shadows, without dramatic glow. Composition: horizontal 3:2, a medium two-person portrait with the tilak gesture as the focus and room around their hands. Style: believable family photography, eye-level 50mm lens look, sharp eyes and natural skin texture. Avoid romantic posing, wedding attire, exaggerated ceremonial props, identifiable real people, extra fingers, merged hands, text, logos and watermarks.
