The same prompt, with and without a picture of my fox

The prompt, word for word, on both sides

A cinematic 3D-animated anthropomorphic fox walking directly toward the camera across the polished hardwood of an indoor basketball court. The fox has plush, detailed orange fur, a white muzzle and chest ruff, large expressive amber-yellow eyes with heavy, half-lidded lids and a deadpan, unimpressed expression - visibly exhausted and unenthusiastic about being there. It wears a navy blue zip-up tracksuit with white side stripes on the jacket sleeves and track pants, crisp white sneakers, and a white towel draped over one shoulder. Its bushy tail sways behind it.

Background: softly blurred gymnasium interior with tall windows flooding hazy morning sunlight across the court, out-of-focus human players shooting and dribbling, a hoop and backboard on the left, retracted bleachers and a rack of basketballs along the right wall. Shallow depth of field, warm volumetric light rays, long shadows and reflections on the glossy painted court lines.

Style: Pixar/DreamWorks-quality character rendering, photorealistic environment, 16:9 cinematic framing, subtle film grain.

The picture I added on the right

A still from a short film of my fox. The prompt describes his fur, his eyes and his tracksuit well. It never says his head is big and round, his muzzle is short or his paws are dark brown mittens, so on its own it got a fox, but not my fox.
