In 1985 Krzysztof Domański co-founded the ephemeral group of artists "CZ-ART", which organised a series of exhibitions: "Zwykli Ludzie", "I Każdy Sam" in Katowice and Częstochowa.

The main techniques in Domański's work have become - based on Renaissance techniques - drawing and painting complementing drawing itself. Since 1986, the artist has lived and worked in Toronto. He has participated in many solo and group exhibitions.

According to Krzysztof Domański, his paintings and drawings are 'landscape studies', which inspire his further search for colour, form and emotion. The artist has been described as a 'visual poet' by Maria Graham, art historian and critic at the Art Gallery of Ontario (AGO). ORION Television in Częstochowa produced a report on the exhibition: "By Walking". OMNI TV in Toronto produced a television programme dedicated to the artist.
