Surreal Billboard Advertisement with Hand Exchange

A complex, ultra-realistic prompt for a surreal billboard advertisement photograph. It depicts a celebrity (Krithi Shetty) emerging from a massive digital billboard, handing a luxury designer handbag to a realistic human hand reaching up from the real world. The prompt contrasts the cool, snowy interior of the billboard with the warm, urban exterior at golden hour, focusing on the photorealistic crossing of the boundary by the handbag.
