Incredible insight into the art of character design using Mickey Mouse as the prime example! It's fascinating how constraints and practical needs, like animation costs, led to such iconic and enduring design choices. Mickey's evolution from simple black eyes to a more expressive character with pupils highlights the importance of adaptation and innovation in animation. Your point about believability over realism in character creation is spot on and crucial for aspiring artists to understand. It's all about bringing characters to life within their universe. Haven't tried my hand at drawing Mickey yet, but you've inspired me to give it a go. Looking forward to more of your creations and insights! Keep sharing your passion and knowledge; it's truly inspiring.
