How can increasing shape density change the viewer’s experience of an artwork?

It may create crowding, energy, or visual pressure.

Shape density refers to how many shapes occupy a particular area and how closely they are placed. When more shapes are concentrated within limited space, the gaps between them usually become smaller and the eye has more visual information to process. The viewer may consequently feel activity, movement, energy, crowding, or visual pressure. Option A is correct because it describes the likely perceptual effect without claiming that every artwork produces exactly the same mood. Option B is generally opposite to the effect of high density, since openness is more strongly associated with spacious gaps. Options C and D are incorrect because added shapes do not disappear and do not make a composition empty. Colour, scale, overlap, and arrangement can modify the final impression.
