Desenho de funil em ilusão de ótica sobre mesa de madeira

A photorealistic image of the optical illusion of a funnel, a black-and-white chess pattern and a perspective drawing lying on the surface of a wooden table. Carefully executed pencil sketch, detailing and nuances of paper texture. Chiaroscuro, emphasizing the depth of the funnel. Realistic reflections of light on a tree. Art with visual illusion, conceptual image. Soft diffused lighting, global illumination, shallow depth of field, clarity. Monochrome color palette, high contrast and detail. An unsettling but fascinating mood. A close-up shot with a funnel in the center of the frame and a table as the background.
