Lauch gangway on the Thames riverbank

I took this picture whilst walking along the South Bank of the Thames near Tower Bridge on my visit to London a few weeks ago. The sun was setting, giving everything a blue-ish hue, and I liked the contrast of the yellow lights inside the gangway. I also really liked the line of seagulls perched on top of it.

Camera/lens settings: ISO 400, f/6.3, 1/80s, 36mm, hand held.
