Create an image of a humanoid figure composed entirely of cubes in various sizes. The figure should appear as if constructed from these geometric shapes, with distinct cubes forming the head, torso, arms, and legs. The cubes vary in size to represent different body parts proportionately, creating a visually interesting and abstract representation of a human body. The composition should be clear, with a focus on how the blocks assemble to mimic human anatomy. The background should be neutral to emphasize the figure.
