In her work, Sirenko explores and re-evaluates the topic of the most common fears and phobias, expressing it through art, as fear is the most powerful and primary, basic human emotion. The key figures in her paintings are stray dogs, which are her personal phobia, connected to the experience of being attacked by a stray dog with rabies. In her works, Krystyna uses her personal fear of stray dogs as a tool to reflect various social fears, turning her own phobia into a source of inspiration and artistic expression. The main goal of her work is to encourage viewers to rethink and overcome their own phobias, creating a space for emotional catharsis and deeper self-discovery through art. She explores her own negative emotions and obsessions through the prism of humour and irony, thereby reducing anxiety.
