{ "prompt": "A creative 3D illusion artwork of a cute young boy stepping out of a spiral notebook page placed on a wooden desk. The notebook has lined paper with handwritten text at the top. The boy appears in a semi-realistic 3D cartoon style, with soft messy brown hair, natural fresh face, and a cheerful smile. He is wearing a pastel oversized t-shirt, high-waisted light grey jeans, and clean white sneakers. His lower body is sketched in pencil on the notebook page, while his upper body looks fully realistic and popping out of the paper, creating a striking 3D illusion effect. Warm soft lighting, detailed wooden desk texture, shallow depth of field, ultra-detailed, high resolution.", "style": "semi-realistic 3D cartoon", "lighting": "warm soft lighting", "resolution": "high resolution", "effect": "3D pop-out illusion with pencil sketch lower body" }
