Not Perfect Symmetry

I decided I wanted to take a blip of something other than flowers or plants. I headed to the river to see if I could find some wildlife but all I found were slugs and snails; I wonder where the swans, ducks etc have all gone. The I looked at textures, lines and symmetry.
I saw this - blue door with benches on either side, but the benches are different distances from the door. Still I like the composition even if the symmetry I was looking for is not there.
