생동감 넘치는 리퀴드 그라데이션 음악 축제 포스터

Vertical social media music festival poster with a clean white background. At the center is a large 3D acoustic guitar shape filled with a flowing liquid gradient in [electric pink, magenta, lime green, and violet], slightly abstracted and organic with a glossy, smooth, puffy 3D aesthetic. Floating gradient music notes, hearts, and sparkle diamond symbols in matching fluorescent colors surround the guitar. Bold large serif display typography at the top reads "[INFINITE LOVE MUSIC FESTIVAL]" with oversized black and gradient-colored letters. Clean minimal sans-serif typography below displays event details reading "[2025 · JUNE 20–22]". Tiny decorative star and sparkle motifs are scattered across the white background, creating an elegant, high-energy modern graphic design composition.
