Stylized mermaid princess with iridescent scales, polychromatic hair, and oversized seashells on her head, floating over a plain white background. Core design largely intact, modified with larger acorn-shaped hands and a swirling, ethereal tail with iridescent sheen and delicate lace patterns. Stylized merman with bright pink and turquoise patterns on his body, big smile, and angular, shark-like dorsal fin, set against a simple, gradient blue background. Core design preserved, modified with glowing aqua stripes on his arms and legs, more detailed texture on his skin, and a pair of oversized, shimmering starfish at his sides. Futuristic mechanical centaur with iridescent, rainbow-colored fur, slender goat-like legs, and gleaming silver limbs, rendered in 3D against a basic, empty black space. Key design elements maintained, augmented with bejeweled airfoil-like wings, weaponized hooves, and dim glowing blue veins beneath the skin, intricate mechanisms visible under the gleaming coat. Elven fairy with overgrown, twisting horns and flowers for hair, delicate, lacy wings, and delicate wings set against a plain background with subtle texture. Core concept building on original, modified with trailing vines and roots for hair, layered diaphanous wings with a verdant glow, and long eyelashes with sparkling, dewy tips. Surreal skeleton with red, Bavarian-style clothing, colorful stringy arms, and oversized boots, floating over a deformed, halved terrain. Retaining core design integrity, modified with swirling, ink-like tattoos, intricately decorated buckles and metalwork, and lighter, unrested colors.
