Miniature Anime Magical Girl Musique

Bright, ultra-saturated anime YouTube-style promotional thumbnail for [Sousaku AI] in a magical-girl music theme, 16:9 aspect ratio. In the center, exactly two cute brown-haired magical girls sit side-by-side, both smiling with closed eyes, sharing wired earphones connected to a single smartphone resting between them; the smartphone screen displays a colorful equalizer with audio playback controls. The left girl wears a yellow-and-white frilly magical-girl costume with wing accents, star decorations, yellow ribbons, and a tiny banana-shaped crown accessory. The right girl wears a pink-and-white frilly magical-girl costume with blue twin-tail ribbons, a star brooch, white gloves, and soft angel wings. Glossy idol anime art style with soft cheek blush, intricate frills, and polished highlights. Explosive rainbow concert fantasy background filled with neon gradients, sparkles, starbursts, glowing music staff lines, oversized floating musical notes, a prominent treble clef on the left, speaker and headphone graphics, horizontal equalizer waveforms, and a piano keyboard running along the lower-left edge. Four specific visible text elements: a huge top Japanese headline reading "[♪AI楽曲生成♪]" with a thick white outline, dark drop shadow, and a pink-yellow-blue gradient fill; a small handwritten-style Japanese tagline near the lower left reading "[音楽の世界へ♪]"; a large curved bottom ribbon banner reading "[Sousaku AI]"; and a rounded white logo badge in the upper right reading "[Sousaku.AI]" alongside a small red origami bird icon. High contrast, dense kawaii visual effects, crisp readable typography, completely filling the frame.
