Create a picture book-style illustration poster with a large area of green forest pattern (with fine texture, creating a quiet atmosphere) as the background. At the bottom of the picture, there is a very small, simple White House (with red window decorations). Through the forest background, the simple house shape and the warm text, it conveys the characteristics of a peaceful and healing picture book. --ar 3:4 --v 7.0 --p 78soi4x --s 50
