Astana enhanced, part 2 - sun and sky

(Astana was a hurried video project where a camera flies through 1300 acres of property. Now, to answer my question, "what if we'd been given more time," I'm enhancing the entire neighborhood.)

The old sky was a simple blue gradient.

The new sky adds clouds and a lens flare effect (sunrays, glow, and lens reflections) for the sun.
In a later step, the sun will be animated to quickly set toward the end of the video, leaving a night scene.
