Rivière works as painter also on portrait. He develops his
research through different kinds of series. He uses mostly black acryl
on watercolour paper, but also chalk on paper or oil pastell on paper. His
purpose in each painting is to experience what a human face can be.
reduction of mouvement, colour and composition represents for him the
possibility to suggest fragments of interior lives. In this context
outside and inside are in mutual pictorial progress.
