Design a beautiful poster for "SeaArt Infinity" with the title at the top in a gentle, flowing script. The background should be a soft, painterly scene, reminiscent of Impressionist art, with visible brushstrokes and a focus on light and atmosphere. Below the title, include the word "Impressionism" in a delicate, artistic font. Use pastel colors and a blend of cool and warm tones to create a peaceful and harmonious effect.
