Tomás Müller has produced several hundred erotic images in a variety of different styles, and has also experimented with comic strips, though none has reached the point of completion and publication. Much of his work includes his trademark smooth skin surfaces and white highlighting to emphasise the tactile quality of his subject matter, and he is not averse to a little light kink and sex play, sometimes leaving the viewer to wonder how consensual it all is.

In 2017 he produced an erotic alphabet – Alfabeto Erótico – which was published in Fierro magazine and produced as a poster by the Red03 art gallery in Barcelona. It was then used in 2023 to illustrate an erotic text by Clara Rodriguez, El Escenario del Vicio (The Scenario of Vice), published by Fuera Registro.
