Illustration of a Prickly Cactus

An illustration of a prickly cactus in a desert setting. The cactus should have sharp spines and a slightly distant, unfriendly demeanor. It can be depicted with a subtle expression or posture that suggests it's not fond of closeness, perhaps leaning slightly away from a person or animal. The atmosphere should feel dry and solitary, with a few desert elements like sand, rocks, and a clear blue sky in the background.
