Tried the classic exercise of making planet earth seen from space. I found this to be an excellent way of getting to know TG2 better since there are many different shaders involved in a small setup.
Land cover, elevation data, cloud map and city lights map from NASA. Specular water map from JHT's Planetary Pixel Emporium. Milky Way panorama from ESO.
I reduced the haze of the atmosphere quite a bit to get to see the surface better. Besides that this is pretty much default values.
Nicely done :)
This is really very nice looking. I like the way you allowed the landmass to be recognizable; and the clouds in the darker areas.
