Sometimes when you’re working in a confined space such as a tiny balcony off the side of an office block you can’t really position lights exactly where you want. You make do with what you have available to you.
Dense cloud cover often results in very bland skies in a photograph. If you wait until after the sun has set and underexpose the clouds you can get a very nice deep blue that works well as a background. You then need to light your subject, and this is where the speedlight comes in. Shoot through an umbrella to soften it up a little and you get nice punchy light that results in a great photograph.
Notice that I didn’t underexpose the background too much, this results in the dark hair and dark clothing of the subject standing out against the background thus a rim / kicker light was not needed. The shadow side of the face is a little dark but having the subject turn her head toward the light helps. A reflector could be used to bounce a little light back if you want.
A great shot with just one speedlight.
