His composition, the concept of shapes, light handling and other features paintings show a significant effect of the work Maulbertsch, whose work he admired. His approach is quieter, the expression of the character rather lyrical, restrained, narrative tuned. Unlike Maulbertsch, Leicher was not affected by the expressive manifestation of
Paul Troger. He was inspired apparently also by other Venetian painters of 18th century, particularly the compositions of
Giambattista Pittoni, and also images of
Peter Paul Rubens. It is most evident on two paintings for the church altar of John the Baptist in
Kroměříž. Its development lacks obvious drama or a representative sample of altarpieces in
Opava parish church of the Assumption, which are often seen as the most perfect, do not lose connection to the
Rococo works of his early creative period. Some critics, however, see more inspiration coming from the works of
Michelangelo Unterberger, a professor at the Vienna Academy, whose work was a kind of moderate variant of the former academic uniform style, especially for it suggests a simple, clear compositional solutions and more lyrical, moderate tone of works by both artists. ==References==
