I find it very amusing how little you all know about how to use the Galaxy Editor and its capabilities.
Also, if you want to change the fog properties, open the data editor, go to terrain texture sets, open whichever tileset you're using, then scroll down that to a little bit past the middle and you'll find the fog properties.
One more thing: maybe lower the bloom threshold just a little bit lol? Perhaps 0.1 or 0.2 would be better than what I presume is 0.0, and perhaps add in a little depth of field.
