YouTube channel ART BANNER, 16:9 wide cinematic layout, kids cartoon style matching the reference character. Adorable little girl character "Pupsa" (use the uploaded reference for face, hair and outfit) standing on the left, smiling and waving. Bright cheerful tropical "Island of Joy" scene: soft pink and turquoise color palette, sunny beach, gentle ocean waves, palm trees, fluffy clouds, a friendly pink flamingo and a cute little crab and a small bubble fish as side characters. Big empty sky area in the center-top for the channel title text. Soft 3D Pixar-like render, warm soft lighting, glossy, high quality, very cute, safe-for-kids, no text. Leave clean space in the middle so a title can be added later.
