Some clip art is pretty cool, but most clip art lacks soul. Most fails any test of style or quality. Clip art cats, lions, people, dogs, cars and trucks are usually mere caricatures of their real selves. These clip art images usually fail to express the essence of an object or a being. Cats appear out of context as silhouettes and simple figures without a window or chair to sit in.
Lions stand up proudly without grass or prey in the background to enhance their grandeur.
Look a clip art person in the eye and there is nothing deeper to see. Dull, staring eyes. The clip art person has no soul. The clip art lion loses its ferocity. The clip art horse loses its spirit.
