Aren't we like that too? Our moods and faces change from the morning to the afternoon, and we are never exactly the same from one day, from one moment, to the next. Our weight fluctuates. Our skin loosens. Our eyes are clear or murky. Our wrinkles evolve. And as we shift our perspective on things, we can be clouded and dark like the mountains at night, or crisp and linear the way they rise from the horizon at first light.
I think we have an expectation that we can achieve a certain "look" that we are pleased with, and then maintain it exactly that way forever. But our bodies and our faces are an ongoing process. There is a daily view, ever-fresh, dynamic, and interesting; We are as curious and wonderful to live with as the mountains, that never look the same, and are always beautiful and new.
I am fascinated by facial expressions and the way we all change visually from day to day, and morning to afternoon, like the mountains, or the surface of a pond.
