Through open lines the object is neither restricted nor entirely formulated.
This „non finito“ has its charm, because our perception works as a permanent comparison. Our brain collects many schemes in the course of time.
The information provided by an image is constantly
compared to the stored images in the mind. While constantly comparing visual information, then standardizing and newly memorizing the images will be identified more quickly next time. So you need to draw only the typical visual features to convey back to the familiar image. For this effect open lines offer themselves.
Open lines give the object space to breathe.
