The work that Tomas does reveals two of his areas of interest. The first is the contrasting relationship between colours on a white background, how the perception of colour changes in relation to other colours, its area, shape etc. He is particularly interested in the relationship of the stain to the other elements of the painting. The second group of works are metacubist works, an attempt to combine elements of different styles on the basis of cubism. Experimenting in the search for new forms of expression, in digital art and in acrylic works made on canvas and paper.
Tomas' main motivation for his artistic work is the desire to express new philosophical, cultural, political, etc. concepts through visual, performing and textual arts. According to Tomas, a conceptual perception of the world is not enough, it has to be realized in paintings, lithographs, performances, among other artistic forms.
