Design a vividly detailed logo of a fox, capturing its elegant features in 4k resolution. The fox should be depicted with fluid lines and intricate patterns that highlight its agility and cunning nature. Incorporate warm, earthy tones like deep oranges and russet reds, accented by subtle hints of silver and gold to add depth. The fox's eyes should be particularly striking, with sharp focus and a hint of mystery. Place the fox in a dynamic pose, suggesting movement and grace, while maintaining a balance between realism and artistic flair.
