Thanks for all the encouraging comments, much appreciated.
I might benefit from a discussion of how, or if, to warm the sunrise tones: It turns out that sunrise along the south coast of Kauai is often a bit wimpy, often accompanied by fog banks that block the rays until the sun is rather high up. In this case I got just a tinge of sun before the sun was blocked by the off shore clouds. So, what to do? Increase the overall color temperature? Increase the hue of the oranges, reds and yellows? Nothing?
