Four Different Styles of Arrangement

We didn't have any class all of September. It happened that I had these beautiful flowers, so I felt the urge to do some arrangements using them. Here are the four different styles.

Naked weeping pine branches (I stripped all the pine needles), St. John's-wort and roses.

Trimmed azalea branch and sunflowers

Willow, pine, and chrysanthemums

Abstract design- rose( in tube) and broken leave
