Craft an Intricate 17th-century Painting in the French Baroque Style

Craft an intricate 17th-century painting in the French Baroque style, portraying a majestic lioness adorned with a radiant silver mane and intense, emotive eyes. The imposing creature is depicted standing gracefully against a backdrop of jagged cliffs and a sky streaked with the hues of sunset. To lend a whimsical flair to this noble composition, a decorative speech bubble floats beside her mouth, elegantly inscribed with the word "purr" in ornate cursive.
