When It Rains It Pours

With this one i though of natural and man made disasters.
I was thinking of doing this initially but didn't know how to go about it. So i just open'd Photoshop and started adding thing.
End result is pretty good in my opinion..

the 15 layers compose of
BG layer(not masked so i didnt count it)
Earth, Sun, 2 meteors, 2 twisters, 1 huricane, 2 craters and 6 Satellites.
The Sun rays and Smog are another 2 but I added them and there not masked in any way.
