His most famous work, 'Pomona Britannica', contains detailed plates of fruit grown in the Royal Gardens at Hampton Court. Brookshaw used a combination of aquatint and stipple engraving to achieve a soft texture. He often placed his subjects against dark backgrounds. This technique makes the colours of the 'Black Prince Grape' or 'Scarlet Flesh Romana Melon' appear more intense. His focus remained on the physical weight and skin texture of the fruit rather than just scientific classification.

Collectors value these prints for their bold compositions and clean lines. The symmetry found in works like 'Peaches' and 'Cherries' fits well within contemporary interior design schemes. These illustrations provide a sense of history without feeling cluttered. Because they were originally intended for large-scale publication, the prints maintain their visual impact when displayed as part of a gallery wall or as standalone pieces.
