A sponge created an evenly spotted texture across the entire watercolour tree area. What should be improved?

Correct answer: Introduce controlled variation in pressure, paint amount, and spacing between marks

The governing principle of natural texture is controlled variation rather than mechanical repetition. Tree foliage and bark contain changes in density, value, mark size, and spacing. Varying sponge pressure and paint load creates lighter and darker impressions, while varied spacing avoids a stamped pattern. Equal pressure would preserve the problem, black outlines would look artificial, and excess water could cause blooms. Therefore option B is best.
