This was playing around with Photoshop layers and using Blender lighting and effects. I did something like this going the reverese - 3D models and Photoshop layers before for Turbine.
I was able to quickly create the layers and then import them as image to plane in Blender.
I seperated the layers based on effects. For this I turned off shadows for lights and layers.

The stars(particles) were the most fiddly. I had to set up a cube and collision to contain them and stop them leaking into the foreground.

The rest was balancing the lighting to keep the effects visible.
