How can I develop my own DC-inspired original characters while maintaining the DC aesthetic?

To develop original DC-inspired characters, immerse yourself in the DC aesthetic by studying various eras and artists. Focus on creating a compelling backstory that fits the DC universe's themes (justice, heroism, moral dilemmas). Design a costume that is iconic, practical, and reflects their powers or personality, often using a limited, impactful color palette. Ensure their powers, motivations, and overall design feel coherent within the established DC framework, perhaps with a clear connection to existing cities or concepts.
