Procedural Clouds 3

Full procedural clouds scene, the background is a procedural cloud system as well.
On this scene I was pursuing to recreating the mood of a sunset.
The scene is lighted with a sun light, environment light, and some point lights to fill.
This scene contains more than 2000 clouds to fill the scene.
I am rendering an animation as I am writing this with Mantra Render, each frame taking around 30 minutes rendering on my MacBook Pro laptop (2.7 GHz Quad-Core Intel Core i7, 16 GB memory )
