Tominz's early works include portraits of members of the nobility and bourgeoisie, but also of simple people.
His influence can be seen in the works of the Slovene painters Matevž Langus and Mihael Stroj.

The style of Tominz's portraits was influenced by late Classicism and by the style of Viennese portrait artists of the Biedermeier period.
The people in his portraits have sharp features and clear forms, but despite this the depictions are realistic, sometimes with an ironic touch.
The backgrounds are filled with landscapes or the city from which the person depicted originated.

Tominz also included objects that hint at the profession or the lifestyle of the person depicted.
Inspired by Jean Auguste Dominique Ingres or Vincenzo Camuccini, he used cool colours and plastic models of people.
He is however best known for his oil painting technique, his precise skills of observation and his rapid style.

When depicting religious motifs, Tominzc relied on graphical templates, the old Italian masters and Nazarene painters.
Amongst his numerous sacred works are altars and other pictures for churches in Gorizia, Prvačina, Aquileia, Kanal ob Soči, Gradisca d'Isonzo, and elsewhere.
