Bright Spring Festival Poster Background

A bright and cheerful spring festival poster background, vertical 4:5 composition, similar in spirit to the reference image but without any text or logos. In the foreground bottom area, there are clear, detailed sunflowers with visible petals and leaves. Moving toward the background, the scene continues with lush green grass, soft greenery, and more scattered sunflowers creating depth. In the upper part of the image, there is a bright blue sky with soft light clouds. From the top edge of the image, two thick hanging ropes come down and hold a large rustic wooden signboard in the center, similar to the reference composition. The wooden sign is blank, clean, and suitable for adding text later. The atmosphere is lively, warm, fresh, and inviting, with soft natural sunlight, subtle glow, realistic textures, slight butterflies and tiny natural details if they fit softly into the scene. Highly detailed, colorful, realistic, festive, premium poster style, no text, no logo, no watermark.
