His work is defined by a moody, almost photographic clarity. He used a technique of building up thousands of tiny dots and lines to create smooth tonal transitions. This method resulted in a porcelain-like quality to the skin of his subjects. In works like "Woman Seated at a Table", he focused on the psychological presence of the sitter. He preferred a muted palette and controlled lighting to create a sense of stillness.

Collectors today value Brockhurst for his technical perfection and the atmospheric quality of his portraits. His prints offer a bridge between classical draughtsmanship and twentieth-century realism. The clean lines and sharp contrasts of his etchings suit modern interiors. His ability to convey a quiet, internal world makes his work a calm addition to a home collection.
