At the beginning, I was trying to understand lights and how to light a scene. I was adding many spots everywhere. I didn't like backlight scenes because renders wasn't good.
Now, less spots or lights I add, better I feel, and I love backligt scenes.
This scene has only the dome and light from the dome come from behind : backlight.
In this scene (and in every recent scene), I play with exposition, environment intensity, environment map, bloom, and burn highlights.
Love this one.
