His artistic approach prioritises line work and structural clarity. In pieces such as Seated Old Man, he demonstrates a keen observation of human form, favouring realistic proportions over idealised features. His compositions, particularly those involving Apollo, often utilise a balanced arrangement where mythological beings occupy the same space as common folk. This stylistic choice creates a visual dialogue between the sublime and the mundane, a hallmark of his printmaking technique that relies on precise hatching to define volume and texture.

Modern collectors appreciate van den Bergh for the historical honesty of his work. His prints offer a window into 17th-century European sensibilities without the heavy artifice found in later academic traditions. The directness of his sketches and the thematic focus of his title pages provide an accessible point of entry for those seeking authentic period pieces that maintain a clear, uncluttered aesthetic.
