Schermer focused on the physical presence of the horse. His work shows a clear understanding of equine anatomy and the mechanics of movement. In pieces like Paard krijgt hoefijzers in een smederij, he captures the smoke and effort of a working forge. He used a restrained colour palette dominated by browns and earthy greys. This direct style avoids the over-dramatised poses often found in historical battle scenes. Schermer preferred to show the horse in a moment of rest or routine work.

Modern collectors appreciate the honesty of his observations. These prints offer a factual look at a world before mechanisation. The images of lanciers and riders provide a sense of quiet discipline. His work is suited for interiors that require a touch of traditional realism. The focus on the horse makes these pieces timeless additions to a private collection. They represent a period of Dutch art that valued accuracy over sentimentality.
