Sketch a large, irregular geometric structure with a strong central mass
Divide the composition into multiple connected sections
Add angular planes, curves, and intersecting forms
Include mechanical-looking elements, arches, and protrusions
Build a layered arrangement with overlapping shapes
Vary line thickness to emphasize structure and depth
Keep the composition abstract and complex
Refine edges and connections between forms
Add tonal shading to separate the different volumes
Balance the drawing so the entire structure feels unified
