Full Ultra HD 8K, vertical 9:16, hyper-realistic 3D cartoon ultra-serene artwork of Mahadev in deep meditation, with delicate facial features and gentle, closed eyes, ash-blue skin softly luminous in the dimly lit atmosphere, a serpent with intricate, scaly texture resting calmly around his neck, its body subtly intertwined with his hair, amidst absolute stillness and shadowed mist, evoking a mood of silence, peace, and timeless calm, with the surroundings fading into a soft, ethereal blur, emphasizing the tranquility of the scene.
