These strokes/marks might blend into one another, but they will tend to create distinct streaks that add texture and movement. Brushstrokes 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. Brushstrokes 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 brushstrokes that are not smoothed over can serve as a reminder of the hand and the emotion of the artist.
