Create a hyper-realistic image of a woman with beautifully styled, long, black hair, dressed in intricate ancient Celtic garb, walking next to a towering, supernatural puma. Both figures move toward the viewer, and the woman's face, body, and entire figure of the puma are clearly visible. The puma, significantly taller than the woman, should exude power and majesty. The woman gently strokes the puma's fur, symbolizing their strong bond and friendship. In the background, show the main street of a wealthy ancient Celtic city, with detailed, sharply textured buildings and citizens in period costumes. The background should not be blurred; buildings and people must be clearly visible. Capture the scene with a wide-angle lens to emphasize depth and grandeur, creating a mystical but vibrant atmosphere of the ancient Celtic era
