My camelia tree on a nasty winters night

I was putting the rubbish out. the night was windy, rainy and cold, the outside lights where lit. I saw the tree and I thought I get my tripod and take a photo.
But the weather worsened, so I just got my camera alone with the 60mm f1.2 lens. I did a few exposures with the AV setting but they didn't come out right.
So i decided to try it on manual. I under exposed by about 4 (increased the speed to 1/60. I liked this much better.
