Ukiyo-e inspired illustration, circular sticker design, anthropomorphic cute unicorn half-body portrait, traditional Japanese woodblock print texture blended with modern digital sticker aesthetics, subtle paper grain, ink-style linework, soft yet detailed rendering. Unicorn has a cute appearance but deadpan, world-weary expression, eyes filled with adult fatigue, smoking a large thick cigarette, cigarette heavily emphasized in composition, smoke rising slowly in elegant curling motion, emotional contrast between cute design and existential exhaustion. Inside circular sticker: beautiful European fairytale castle background, slightly dreamy and atmospheric. Unicorn surrounded by a soft rainbow-colored magical aura, glowing gently. Outside the sticker is pure solid white background, clean cutout sticker look, balanced composition, high detail, fusion of ukiyo-e art style and modern kawaii illustration.
