### Full prompt
```text
Using the figure in the reference image, generate a six-grid evolution diagram showcasing the entire process of sketching art creation, vividly presenting the six key stages of a figure's transformation from sketch to finished product. The drawing should begin with a few initial dynamic structural lines and geometric generalizations, gradually transitioning to the establishment of the outline, the establishment of light and shadow relationships, and the in-depth depiction of details. Finally, in the sixth stage, a complete and exquisite pencil sketch portrait with delicate brushstrokes, three-dimensional light and shadow, and realistic texture will be presented, thus fully demonstrating the progressive beauty of traditional painting from nothing to something. The sketch stage should occupy a smaller portion of the image to ensure sufficient space for the final completed work.
