Sketch a simple geometric shape for the crystal base
Add angled faces around the base
Vary the lengths and widths of the faces
Draw sharp, clean edges
Use straight lines for faceted surfaces
Add smaller crystal shapes around the main crystal
Overlap some crystals for depth
Include pointed tops or jagged ends
Erase guide lines and refine the outline
Add light shading on one side
Leave some faces unshaded for highlights
Darken the edges and lower areas
Add cracks or internal lines if desired
Keep the shapes asymmetrical for a natural look
