What effect may occur if a drawing contains too many middle tones but few dark and light values?

Correct answer: The drawing may look muddy and less impactful

Value range is the span from the lightest lights to the darkest darks. If most marks remain in the middle, adjacent forms have little tonal separation, so the drawing loses contrast, depth, and visual emphasis. Option A is correct: it may appear muddy or flat. A wider, controlled range can improve clarity, but middle tones alone cannot automatically strengthen perspective or remove the need for structural lines.
