Leonessa giocosa in vestaglia che festeggia con champagne di compleanno

A vertical digital cartoon illustration, 9:16, depicting a playful-looking lioness, sitting relaxed in a large armchair. She wears a plush white robe with a shiny crown slightly tilted on her head. She holds a champagne glass on one paw. At the top is bold, decorative text in English, free of errors and distorted letters, easily legible and clear: Happy Birthday! A cheerful, colorful, and well-thought-out vector poster with warm lighting. Create your own congratulatory phrases around the poster. The composition is balanced, the text is easy to read, and integrated into the design.
