Broad strokes/marks can impart a sense of the boldness and strength of the artist. If they succeed in also creating the impression of an object in a representational piece, they can impress the viewer with the bravura of the artist.
Broad strokes/marks might blend into one another, but they will tend to create distinct streaks that add texture and movement. Broad strokes/marks can have vastly different qualities from one another... tapered or not, thick or thin paint, short or long, soft or hard edges, straight or curved, shaky or controlled or energetic.
Broad strokes/marks of uniform quality can be used by an artists to create rhythm and overall order, or varied strokes can be used to create visual interest and/or to more accurately render what the artist sees or imagines. Regardless, the presence of broad strokes/marks serve as a bold reminder of the hand and the emotion of the artist.
