Đôi cá heo hoàng hôn

A highly detailed vector illustration of two dolphins gracefully leaping out of the ocean, forming a dynamic circular composition. The dolphins are sleek, glossy, and vibrant blue with smooth gradients and realistic highlights, their bodies curving elegantly toward each other as if dancing in harmony. Water splashes dynamically around them, with stylized droplets and flowing wave shapes creating a sense of motion and energy.

Behind them is a stunning sunset over the ocean horizon, with a warm gradient sky transitioning from deep orange to soft yellow and pink tones. The sun is low, partially touching the water, casting glowing reflections across gentle ocean waves. Soft, stylized clouds float across the sky, enhancing the dreamy atmosphere.

The entire composition is framed within a circular ornamental border made of fluid, splash-like shapes, with small decorative droplets scattered around. At the top of the circle, a small red heart symbol adds a romantic touch.

Art style: clean vector illustration, bold outlines, smooth shading, vibrant color palette, slightly cartoonish but polished and modern. High contrast between warm sunset tones and cool ocean blues. Symmetrical and balanced composition, centered subject, high detail, crisp lines, soft gradients, no noise.

Lighting: soft sunset lighting with warm highlights and subtle reflections on the dolphins' bodies.
Background: minimal beige/neutral tone to emphasize the circular artwork.

Ultra high resolution, sharp focus, professional digital illustration, poster design style, aesthetically pleasing, harmonious color balance.
