First I got my idea: red dress, evening lights, modern buildings, and an elegant mood. Looking for a fashion photoshoot location I found this place on the Thames shore right on the other side of Canary Wharf, really beautiful before the sunset but also after when all the lights turn on.
It was just the model and I so I had some struggle with the lights, the wind was strong and cold. The model had to hold her pose in that freezing weather to capture the picture with a slow shutter speed 0.3 sec.
You can see a before and after of one of the images on my retouching page.
