one light after dark

I haven't shot much lately and have been itching to get the camera out.
A new profile photo for facebook is always a good excuse and it worked tonight.
I set up one light (sb flash) bounced into an umbrella and up fairly high placed to the left of frame.
I wanted to capture some blue in the sky and there was not much there so had to shoot at f1.4 with a 50mm lens.
I set the flash to its lowest setting and used a long shutter speed, 1/10 sec i think to bring up the sky.
Hardest part was focusing as it was dark out and camera was searching alot. I had a couple shots that i really liked that were out of focus.
