He seems to be best known for his historical paintings, but Internet image searches turned up a number of works dealing with Don Quixote. These subjects are featured below.
Moreno Carbonero's style varied somewhat according to subject matter. The historical images have a near-Academic feeling, whereas his Quixote pictures have more of an illustration cast. He also painted many portraits, but examples seen via the Internet varied considerably in technique.

His major history scene.
Conversión del duque de Gandía - 1884
