Pencil sketch illustration of lion

Create a stylish and dynamic pencil sketch illustration of a [Subject/Animal], rendered with sharp, precise, and confident linework that captures its essential form. The subject should be depicted in a state of dynamic motion or poised action, viewed from a dramatic low-angle perspective to emphasize its power and presence. Utilize strong, directional lighting to create deep, well-defined shadows and highlights that enhance the three-dimensionality.
The background must be a clean, pure white to keep all focus on the subject. The color palette is strictly monochromatic, relying solely on the graphite shades of the pencil. The overall style should be a minimalist and impactful technical sketch, focusing on clean lines, bold contrasts, and a modern, architectural sensibility.
