From these images I also feel the emphasis on seasonal change through the soft gradations of color and varied arrangements. The first image feels like the rosy blossoms of early spring pushing their way up as the warm heat of the sun radiates from above. The second image points me to the most grey of foggy days. In the third image I feel blown back by an explosion of life as spring finds its stride.
In the fourth image I feel the heat of summer, the sweat of lovers in bed without the benefit of air conditioning. In the fifth image I feel the butterflies themselves are fading away as autumn, that harbinger of death, strolls in. The last image below feels like a pile of debris in the cool winter, coming alive. I am reminded of the character Marjory the Trash Heap from Fraggle Rock, and her endless offers of sage advice to those in a predicament: Bring me your troubles, bring me your pain, bring me your woe. Somehow butterflies ease the suffering.
