Steenhoff used a disciplined approach to draughtsmanship. Works like Boomstudie and Studie van een olm demonstrate an interest in the skeletal structure of plants. She avoided the hazy atmospheres of her contemporaries in favour of clear lines. This precision appears in her portraits too. Portret van een man met pet en pijp captures character through steady, unsentimental observation. She balanced these studies with rural scenes like Waterput bij muur to document quiet Dutch corners.

Modern collectors value Steenhoff for her restrained aesthetic. Her drawings of trees and meadows suit contemporary interiors that prioritise natural textures and muted tones. She focused on the anatomy of plants rather than a romanticised view of the countryside. These prints provide a sense of calm and order. They appeal to those who appreciate the intersection of scientific observation and art.
