Soft, naive-style painting with peach countryside landscape. Tranquil, minimalist.

Design a soft, naive-style painting for a wallpaper, using a light pastel peach as the dominant color. The countryside landscape should feature rolling hills, gentle fields, and simple farmhouses, all depicted in warm, soothing tones. Trees and small details should be delicately drawn, with the peach sky casting a calm glow over the entire scene. The overall design should evoke a sense of tranquility, with an emphasis on soft lines and a minimalist, pastoral charm.
