Add highlights: With a generous
amount of white on the tip of a small
palette knife, I applied a highlight on
the nautilus shell, spreading the paint to
follow the curvature of the form.

Add refl ections: Using the same colors that I’d used for the mother-of-pearl area,
I rendered the refl ections on the table with scumbled brushstrokes.

Incise texture details: I incised a few more lines to simulate the rough exterior of the abalone,
fi nishing Nautilus and Abalone (oil on board, 10x13).
