"Illustrate a modern graphic novel concept of an anthropomorphic chihuahua depicted with a more human-like posture as he burrows under a blanket, simulating a mining activity in a cave. The chihuahua exudes determination and confidence, featuring a soft, stoic expression and a relaxed, upright stance. His attire includes a miner’s hard hat and headlamp, goggles, and he holds a symbolic pickaxe. The style should be minimalist with bold, clean lines in monochromatic yellow, capturing the adventurous spirit and personality of the chihuahua."
