a surreal and vibrant cinematic photo of a birthday banner with a vibrant and imaginative flower design outside, blending surreal photography with photorealistic elements, and a subtle film grain texture, featuring a mix of pastel and neon colors with delicate petals and intricate details, against a soft focus background with a shallow depth of field, capturing the essence of a dreamlike celebration, with the banner itself having a bold and playful font style, and a delicate ribbon or string attached to it, swaying gently in the breeze, surrounded by a few scattered flowers and leaves, under a warm and cozy lighting with a slight glow effect.
