Silhouettes in the sky

So lately we had some pretty bad weather here and there was loads of rainbows. I managed to miss all of them being at work or just not having my camera with me  
Yesterday a thunder woke me up and when i got out i saw a rainbow. Certain i wouldn't miss it this time i got my camera and got 1 shot just before it disappeared... and it was out of focus Determined that i wouldn't come back in without something i snapped this one and after some Lightroom+Photoshop love here it is
Hope you like it!
