Other than OCF (which is a pain at the beach, especially with no assistant) I'd like to enhance an existing sky at sunset or sunrise. I've played with Hue/Sat, Channel Mixer and Color Balance layers, but perhaps I'm not using a light enough touch, I keep getting either nuclear colors or effects so faint it's hardly worth doing. I'm pretty sure this style is achieved from an existing sky, rather than a replaced one (or adjustments done to a sky image used for replacement). These colors are a touch stronger than I'm trying to get but the idea is the same:

Is this same one of mine viable for comparison?
