ユニコーンの骸骨がコンクリートの壁にネオンカラーの虹色の煙を吹きかける

Street art graffiti on a grungy concrete wall. A full-body anatomical skeleton of a unicorn, complete with a sharp, spiral-grooved horn on its skull. The unicorn skeleton is facing away from the camera but looking back over its shoulder. A massive, vibrant, volumetric cloud of neon rainbow smoke is bursting out from beneath its tail area, spraying across the wall. Hyper-realistic graffiti style, drips of colorful paint, street tags, masterpiece.
