create a realistic winter atmosphere with a significant layer of naturally accumulated snow covering the ground yard landscaping roadsides rooftops terraces and other appropriate horizontal surfaces the snow should look natural soft and physically realistic with varying thickness and subtle uneven accumulation preserve the original architecture site layout roads sidewalks and surrounding environment without radically changing their design or geometry add visible snowflakes falling through the air creating a realistic active snowfall effect the snowflakes should vary naturally in size sharpness distance and visibility with some appearing slightly blurred in the foreground and others more subtle in the background creating realistic depth and atmosphere maintain a cold winter environment while preserving the original colors of the building and facade as closely as possible add realistic interaction between the snow sunlight glass surfaces windows landscaping and architectural materials include subtle reflections and highlights on the snow and the fully glazed swimming pool structure the final image should look like a high end ultra photorealistic architectural photograph taken during a beautiful snowy winter day with accumulated snow on the property and clearly visible snowflakes falling in the air
