How to say that calligraphy looks good when it is big?

Calligraphy is very big. It's nice to say that I feel the pleasure in calligraphy from the change of ink color and lines. Full pen and ink: pen and ink are used freely and full. Describe calligraphy and poetry. The dragon and snake in the pen: the dragon and snake jumped into the pen. Describing calligraphy as vigorous and free and easy can describe calligraphy.
