Use a large brush loaded with medium dark ink to paint the leaves.
I start from the upper left corner quickly and roughly stroke downward.
The upper right corner is just some unruled random strokes.
Then apply very very very light red on the petal. At the tip of the petal, I dot darker red (just a little bit darker, not too much). The darker red mixes with the lighter and they together go out of their boundary make me feel the air is evaporating and the water is flowing.
Dab some very very very very light green between the flower and leaf
