A flower has a character and a personality, which can easily be paralleled by a human individual.
And like flowers, humans exhibit gracefulness, unruliness, colourfulness, simplicity, power and subtlety.
I look for these characteristics in both.
 
'Whether in appreciation or in its creation, flower painting induces tranquility and purity
in the mind and stimulates serenity. It has long been considered one of the joys of life'
~ Chou Shih-hsin
