People holding flowers are a favorite theme among many illustrators and are often tagged #手に花 (literally “flower in hand”) here on pixiv. The image of delicate blossoms being gently held up to a character's face can often give them a mysterious or melancholy aura; on the other hand (wink!), it can give them a flamboyant flair if they’re drawn twirling a stem between their fingers. Either way, flowers make excellent props and supply the imagination with endless possibilities.
Below is a series of drawings featuring various characters posing with flowers. In some illustrations, the color of the flowers even matches the character’s eyes!
