Three Containers Arrangement - Color in the Same Tonal Range

Using three different sized wine glasses as my containers. They are transparent (10.5”x 5.5”), green and deep purple (9.5”x 3.5”).  For the materials, I used lilacs, iris, bitter sweet vine and dried vine, and arranged them into three glasses with good balance and harmony!  The glasses of materials are in the same tonal range in color too!
