Both a day shot and a night shot

I think I'm going to do some more on this, that why I posted it here..
Here's the night image:
Two Meshlights and a Sun (acting as moon)

And here's the day image:
Still two meshlights and a Sun

In the night shot I've given the Meshlights a gain of 100000000.
And in the day shot I've used a gain 100.
Pretty simple and stylish

Well, any comment is welcome

Enjoy!
