Wow, @lincolnlens, that is so neat you were able to be in such a great location to see the northern lights!
Aurora-d.jpeg – This one is by far my favorite shot of the ones you submitted. Like @loganlamar said, I’d dial down the saturation. Also, I’d see what I could do to prevent haloing from happening around the dark trees. It’s only happening on the right side of the photo. The trees in the center and left of center look great! But the way the sky suddenly becomes dark right above the trees looks unnatural to me.
