4k photograph of a young woman sitting by a window on a rainy day. The natural light from the overcast sky outside falls through the rain-soaked window and casts a soft, diffused light on her face. This light emphasises the subtle nuances of her facial expression - a mixture of happiness, contentment and serenity. Her eyes gaze out of the window, reflecting a hint of the grey, rainy world outside. The room around her is in soft shadow, emphasising the light on her face and her friendly mood. Her hair falls loosely over her shoulders and she is wearing a comfortable, casual outfit. The overall mood of the portrait should be happy, with an emphasis on the interplay of light and shadow to enhance the emotional depth of the scene.  --s 750
