How you put the paint on the paper is as important as (if not more) than what you choose to paint. Any subject matter can make a successful painting if the artist has the vision and the confidence to paint it in a way that is compelling.
To achieve this, one must have confidence: in their drawing skills, their command of form and value, proportion, perspective and color harmony. A tall order that can only be achieved with constant practice. Try to practice without worrying about the outcome. Place your strokes with a bold hand, it’s only a piece of paper or canvas, don’t be afraid to make a mistake. Tentative strokes are not compelling, and they are always visible. Try to lay down strokes with a gestural, confident hand, don’t hesitate, hesitation is always visible. Make a mark, and let it stand.
