Like a world soaked in greens. Spectacularly flamboyant, the stars, the reflections, the angled beach and mountains. A precious gift from the north. On top of all that, the brighter tones form a star, too.
Personal second favorite of the challenge.
Northern lights, always gorgeous. And in this one you have a nice spread across the image with a great silhouette of the mountains, plus the reflection in the lake. A beauty. (small point: strange however that I see only one light spot in the lake, I would clone it out or soften it)
