Artiste Peignant un Royaume Sous-Marin Magique

A [3D Pixar-style digital illustration] of a [young female artist with curly brown hair] in a messy bun and a paint-splattered apron, dynamically swinging a giant paintbrush across a large canvas. A vibrant, [magical splash of teal, turquoise, and deep blue watercolor] erupts from her brush stroke, swirling upward into a detailed underwater kingdom. The splash forms coral reefs, a winding stone staircase, and a majestic seashell castle, with glowing bioluminescent jellyfish and tiny fish floating in mid-air above it. The scene is set in a cozy, sunlit artist's studio with jars of colorful paint, a hanging lantern, and blurred art supplies in the background.
