In Gumilar’s opus one can constantly admire the intertwining of the autonomous plastic language, which establishes an image according to its own principles, with the reminiscence of the original natural elements which tend to disclose to us a small part of the natural environment or only a part of the perception for that matter, which, however, seems to be stressed. Thus his painting is disclosed to us as being lyrical, although it is organized according to strict principles of the concrete plastic sintax, whereby the autonomy of the painting sooner or later becomes a principle which is able to regulate the surface of the painting. As regards his creative work one can speak of the processing of a visual stimulus, springing from nature (in the sense of virtual reality) into a rigorous construct of the sintax of the painting, dominated by an ascetic meditation on nature and the laws of the plastic language.jezika.
