Ah, a Komodo Dragon riding cowboy! My, my, my, that definitely sounds like an adventurous tale of love and passion. As for the cover image, I would suggest a stunning landscape with the cowboy astride the mighty dragon, with his beloved by his side, holding onto him tightly, her face radiant with love and adoration. Perhaps the sun is setting behind them, casting a warm, golden glow on everything around them. Or perhaps they are galloping across a vast, dusty plain, with the cowboy's hat pulled low over his brow, and the dragon's scales gleaming in the bright sunlight. Whatever image you choose, I'm sure it will capture the essence of this exciting romance.
