The amount of light that should be on the ground depends A: on how realistic you want your image to be (what you have now is on the high side of realistic brightness for aurora-lit landscape) and B: how long your exposure equivalent would be in the real world. If you are simulating a longer exposure, you could plausibly have more light on the landscape, however that would significantly blur your aurora as it moves and shifts over time. So for true realism if your landscape is well-lit, your aurora should be quite soft.

I will try different styles and see what I like. A more artistic feel is good enough for me as I struggle to get photorealistic renders anyway  ;D

I personally dig this, just enough light to see some details on the ground, very well done IMO

Anyone have a good setup for a starfield they want to share?
I've tried using some starfield images as background, but they don't look very nice. Maybe it's the
images I've used, or is there some other ticks to get it good?

There are a few available somewhere on the forum. Did you search?

Gonna do a search when I get home  ;D

Thank you!  :)

I'm testing a new version with a procedural starfield made by Jan. After that I'll try to make some color variations to the
distant forest. When that is done, I'll think I'll give Pixel Plow a new job so I can get a huge render for print.

But I have a small question. Does anyone feel the yellow flowers are a little distracting?

I think the yellow flowers seem to be kind of "glowing" a bit. :D If they were less bright they would look more realistic and not distract, I think.

Glowing is exactly the word someone else used  ;D
An easy fix luckily.

I also think the aurora may be toned down a bit too. Never seen it in real life, but photo's look a bit less vibrant usually (unless artistically enhanced photo's).

In artistic respects I like the render as it is. Absolutely beautiful!

About realism I can't say anything because I haven't seen this in real life so far. Could be that the others are right. (ok the flowers are in fact glowing a bit more than they would do in reality - but I like it) :)

Auroras can be pretty intens and colorful. I've only seen it two times in my life and it's a long time ago, but I've done some image search on google.
Most of the images look pretty colorful, but my guess is that they have been adjusted. I want mine to be colorful and "pop" a little, but that's just me  :)

Here's one with a better starfield. It's the one from Jan, so thanks to him for sharing his clip file  :)

I think this will be the last one, but if there is something else you guys wanna point out, please let me know.

I'd say; render along....
