The bloom is looking off to the lower right, almost like a non dominant hand trying to write something. It's unusual this orientation, sometimes the slightest shift can bring in new insights.
The pink outer petals creates a frame and a contrast to the inner petals. There is a harmony here even though there is a transition in colour. Frilly outer petals imply a playfulness, movement, whimsy.
Delight, joy, wonder, newness - this composition supports all that. Nature doesn't make a mistake.
The reason this painting works, colour wise, is because nature sorted out all the nuances ahead of time.
