His work is characterised by a delicate handling of light and atmospheric perspective. Works such as S. Valery, View from the Banks of the Somme demonstrate his ability to capture the specific geography of northern France with soft washes of colour. Fielding often chose subjects that balanced architectural detail with natural elements. His compositions in Cottages at Castle-Combe show a careful attention to texture and form. He preferred muted tones that allowed the structural clarity of his drawings to remain visible.

Modern collectors value Fielding for the quietude and historical accuracy of his views. His prints, such as Sarnen and Cottages at Castle-Combe, provide a window into the rural topographies of Britain and Europe before industrialisation. The restrained palette and precise draughtsmanship make his art suitable for contemporary interiors that require a sense of calm. These works offer a connection to the traditions of the English watercolour school while maintaining a sophisticated, international perspective.
