Seder's early works are influenced by Marino Tartaglia and Post-Sezanism. The period of activity in Gorgona is marked by non-figurative paintings, initially richer in color, and later monochrome, thick spreads, with rudimentary signs, on the trail of enformel. In the 1970s, he returned to color and created works free of gesture and a sensed motive. He is one of the pioneers of the new painting, whose expressiveness is emphasized by open color, pasty spread and expressive motifs. In the 1990s, he introduced biblical themes. He is also the author of church stained glass windows, and a number of works on biblical themes in Bosnian churches and monasteries.
