Create a friendly character that resembles a doctor with a playful twist. The character, named Dr. Eco, should have a warm, approachable expression, with a stethoscope shaped like a pair of headphones hanging around his neck. Dr. Eco wears a lab coat, but instead of being plain white, it has subtle, colorful patterns representing sound waves or music notes. His hair is neat, and he has glasses that give him an intelligent yet kind appearance. Dr. Eco is holding a tablet or a device showing a game screen, indicating his connection to auditory training
