Reflections in puddles are always interesting, in this case the addition of the first fallen leaves of Autumn make for a richer version of the London skyline. I wish I hadn’t placed the lamp-post right bang in the centre but I don’t want to crop the tree at the left because I like the feeling of being within a dark space looking out to the bright scene across the water. Its only now that I realise that the Thames itself isn’t visible but if I had taken the shot from standing instead of crouching in order to see the water, I wouldn’t have captured the reflection.

That reflections is almost like a mirror!
this is a great photo.
Thanks Kris, iPhone, in the car, stopped at traffic lights, through the window = challenging.
