Lich by the Moonlit Lake: Dark Concept Art

Dark fantasy concept art of a lich standing by a moonlit lake. The lich wears torn, rune-etched robes, a bone-white skull visible beneath a hood, with a pale necromantic glow around its fingers. It grips a gnarled staff crowned with a glowing blue crystal; wisps of blue-green energy drift from its hands and form faint phantoms hovering over the water. The lake is still and glassy, reflecting a silver moon and a starry sky as fog drifts across the surface. In the distance, ruined marble pillars overrun with ivy and weeping willows line the shore. The lich's phylactery hangs at its belt, pulsing with light. The atmosphere is cold, ethereal, and ominous; color palette includes deep midnight blues, slate grays, cold greens, and electric cyan runes. Lighting is high-contrast with backlighting from the moon and the lich's glow. The painting should have painterly textures, crisp detail, and a cinematic composition, with the lich as a solitary sentinel guarding the lake.
