Excellent! I certainly like this view of Fist-of-God, and the setting is
very credible, as is also the atmospheric effect you have been able to
generate.

I have been experimenting these last days with media, confined to a ring
simulating the atmosphere. The results are not really satisfying, and
becomes very difficult (and slow) when a cloud layer is added. I came to the
conclusion that, in any case, the atmospheric effect would resemble a half
sphere around the camera (like you did). Further away, it would not count.
So, I am back to start in that respect, but I learned a lesson.
