This painting uses a monochrome palette to think about identity, the painting is black and white but individuals rarely are.
The sitter is ambiguous: male/female, vulnerable/confident, questioning/accepting. The dramatic light and unusual canvas size would make this a feature on your wall.
In my painting I aim to use dramatic light and I’m interested in the indication of form in the mind’s eye. In portraits especially I like to have a sense of narrative, capturing a moment of realisation or decision.
