His work is defined by clear lighting and topographical detail. In "Soldiers Fighting with Swords on Horseback", Becker captures the physical energy of a cavalry charge. He used thin paint layers to create a smooth surface. This technique avoided heavy textures and kept the focus on the subject matter. He often placed small figures against wide horizons to create a sense of scale. This approach ensured that his compositions remained legible even when depicting complex historical events.

Modern collectors value the sense of order and space in his compositions. His paintings offer a calm alternative to more chaotic Romantic works. The "Church in the Distance" shows his ability to create depth through subtle colour shifts. His prints suit interiors that require a traditional look with a clean finish. They provide a window into 19th-century history and offer a balanced aesthetic for contemporary homes.
