벽에 빨간 하트 풍선을 든 작은 기운 로봇

A realistic Banksy-style painting of a small, patched-up robot against a concrete wall. The robot's body is made of old, dented metal plates with cloth patches and rust stains. It stands alone and holds a single red heart-shaped balloon that floats gently upward. The robot's eyes are dim, and its face has a subtly sad expression. The overall composition is gritty and textured, with a soft contrast between the red balloon and the muted tones of the urban background.
