a dark and foreboding image of a lion imprisoned behind thick, vertical bars. The lion should be positioned further back in the cage, its full body visible but smaller in the frame. The background should be a misty, gloomy blue-gray, creating an atmosphere of isolation. The lion's silhouette should be mostly dark, with its mane slightly disheveled, suggesting a wild, untamed spirit. Its eyes should glow faintly, piercing through the darkness with a hint of defiance. The bars should be prominent in the foreground, stretching from top to bottom of the image, casting long shadows. Add some subtle, wispy clouds or fog in the background to enhance the somber mood. The overall tone should be muted and mysterious, with the lion as a powerful yet distant presence behind the imposing cage.
