A splattered star field needs both large and small dots. Which method is most controlled?

Correct answer: Vary paint load and flick strength in two controlled stages

The governing concept is deliberate variation: droplet size depends mainly on paint load, brush moisture, distance, and flick force. For small stars, use a lighter load and gentler flick; for larger stars, use more paint or a stronger, still controlled flick. Repeating one heavy motion cannot create both sizes, pouring is unpredictable, and a dry brush may not release paint. Thus option D is the most controlled method.
