Alfonso has been painting with the Ngaruwanajirri group since 1997. Subject matter of his paintings is drawn from his environment: Tutini (pukumani poles), carved heads, figures and birds as still life groupings, local landscape including houses, trees, boats, bicycles, planes and cars. Alfonso uses bold brush strokes, generous paint application and applies black lines over broad areas of colour, finishing with another layer of colour. His paintwork has a strong textural effect.
