His approach combined the strict discipline of Neoclassicism with the softening influence of the Biedermeier period. He favoured watercolour and sepia tones for his portraits and mythological scenes. His work is characterised by a precise, fine-lined execution that avoids the heavy shadows common in Baroque art. He focused on clarity and the subtle graduation of light. This technique gave his drawings a luminous quality that captured the quiet domesticity of 19th-century Viennese life.

Modern collectors value Agricola for his technical precision and his ability to convey character within a small frame. His prints offer a window into the transition between the formal courtly style and the more intimate realism of the middle class. The clean lines and restrained colour palettes of his work suit contemporary interiors. These pieces provide historical continuity without the visual clutter of more ornate periods.
