He entered the studio of the French painter Charles de la Traverse, who worked for the Marchese of Ossun, the ambassador of France in Spain. Unfortunately upon returning to Madrid, despite becoming a teacher in the Academia de San Fernando at age 33 years, he mainly received royal commissions to paint and engrave vistas of ports, the Spanish equivalent of vedute, and also of planned works of construction. For some years, he was banished to Puerto Rico, where he trained the painter Jose Campeche. He also painted flowers in still life and genre paintings called bambochadas for their focus on the customs of the underclasses.
