What I like is the gradual transition from left to right. The middle plate has both light and darker areas with the plate either side in keeping with those tones. I thought about placing the darker one into the middle, but it did not look as good.
Fantastic...the "mood" gets darker, protective or defensive would be my guess
Arms crosses, then, the other way woth the frown letting up, then, girl behind her knees in the end...she even sinks a little on the plane
