His artistic approach relies on the balance of negative space and bold, deliberate lines. Schönfeld avoided complex ornamentation, choosing instead to focus on the structural essence of his subjects. This method creates a sense of stillness and weight within his compositions. His work in lithography and woodcutting demonstrates a mastery of tonal contrast, where the absence of ink is as significant as the marks themselves.

Modern collectors appreciate the honesty and technical skill found in Schönfeld's prints. His art fits well in contemporary spaces that value minimalism and clear forms. Because his work avoids fleeting trends, it remains a stable choice for those looking to build a collection of German graphic art. The physical presence of his hand-carved lines offers a tactile quality that digital reproductions cannot replicate.
