Doodle Style Cello Concerto Concert Illustration

Full prompt

A whimsical, naive doodle-style concert illustration capturing an expressive cello concerto performance through an abstract, stream-of-consciousness lens. In the center, a young man with curly hair passionately bows a large cello; to his left, a brown-haired girl in a flowing blue formal dress plays the violin; to his right, a young man in a clean white t-shirt plays the viola. The visual language uses broad flat color blocking, organic polka dots, textured grain, and a traditional salt-wash watercolor technique over a deep navy-blue background dusted with fine white speckles, arranged in an artistic 9:16 vertical poster layout.
