OK my first image for ages and it's not even a finished work

I started out intending to make some tests with the new cloud lighting inputs but some chance settings gave me this. For me these clouds have that after the rain evening glow and i want to make something of that, I've a couple of ideas but am open to suggestions.
Definite to do:
Change default landscape (We are very quickly going to get sick of that mountain).
Fix atmosphere quality.
Finalise cloud settings.
