anime illustration, great quality, best quality, A full body shot of a cute chibi girl character swimming gracefully underwater in the ocean, captured from a three-quarter underwater angle with bubbles rising around her. She has exaggerated large head and small body proportions typical of chibi style, short pastel hair flowing with the current, wide sparkling eyes full of joy, and a big cheerful smile with rosy cheeks; wearing a skimpy colorful bikini top and bottoms that cling to her petite frame, barefoot with tiny toes pointed as she kicks her legs playfully. Her arms extend forward in a streamlined swimming pose, small hands cupped to propel through the water. Surrounding her is a crystal-clear turquoise sea filled with schools of tiny colorful fish, swaying kelp strands, scattered seashells and coral fragments on the sandy seabed below, shafts of sunlight piercing from the rippling surface above creating caustic light patterns. Vibrant underwater blues and greens palette, high detail on water refraction, bubbles, scales and textures, dynamic motion blur on fins and hair, serene and playful aquatic atmosphere.
