His work often features a balance between architectural ruins and the natural world. In pieces like Ruins of schloss Hartenstein and Grotto near Sorrento, Carmiencke uses clear lines to define structure against soft skies. He avoids the dramatic exaggeration common in Romanticism. Instead, he focuses on the quiet geometry of a Church with Gothic Choir or the mechanical simplicity of a Mill.

Collectors value Carmiencke for his technical clarity and calm compositions. His prints, such as Two Oaks or River Bed with Three-Arched Bridge, offer a sense of order. These works provide a window into nineteenth-century rural life without excessive sentimentality. His etchings translate well to modern interiors because of their graphic quality and neutral colour palettes.
