Looks good, but the sun needs to shine more trough the clouds at the edges,
right now, the glow immediately stops, when the sun comes near a cloud's edge.
Furthermore, the clouds themselves should glow at the edges near the sun, that
could be obtained by using a pigment that is not translated with the clouds.

That is neat. Now I see what you were talking about at the chat room.
Media might do a good job of having a glowing edge to the clouds, but then
there goes the use of a phong highlighting on the shadow side.
This sort of opposite-side-of-lightsource highlighting could be a great
feature. Many times I've wanted to show a normal on the shadow side of a
semi-transparent object.
