Taking a palette knife to realism, he aims to make it abstract, "to extend the paint beyond the boundaries of the form we know".
A striking example is Van Zyl's Underdog, a gnashing depiction of a hyena, which he says is usually perceived as an underdog. He means to show "the strength and beauty in what society might perceive as lesser or dark".
Another piece, Freed, continues the theme of letting go, this time of expectations, and not judging.
Van Zyl studied graphic design in the early 1990s, ran his own design agency for 17 years and returned to painting full time in 2010. In a little more than five years he has created more than 400 artworks, of which about 200 are oil paintings, including landscapes, still lifes, portraits and self-portraits.
The bucolic simplicity of a town such as McGregor seems a perfect setting for his new exhibition.
With its lime plaster walls and old Oregon pine windows and doors, La Galleria, opened in March as Dani's Photos Studio and Gallery, a space shared by exhibiting artists.
