Undead Necromancer Riding Frost Dragon In Ruined City

An undead dark elf necromancer, riding atop a monstrous, scarred frost dragon. The elf wears ornate, dark blue and gray armor with glowing purple runes, and wields a wickedly barbed, massive spear. He has glowing purple eyes and a grim expression. The dragon has sharp teeth, glowing purple eyes, and visible wounds. The scene is set in a ruined, gothic city under a cold, overcast sky with light snow falling. Distant buildings are silhouetted, and faint orange light from fires glows in the background. Digital painting, highly detailed, dramatic lighting, fantasy art, dark atmosphere.
