What I was trying to do

I saw the potential for the arm movements both real and constructed and happily they aligned with the passer-by just as I pressed the shutter. I also liked the hoarding saying "your home away from home" whilst everything still appears to be under construction - plus who doesn't love a robot called Alex!

What worked

That all the elements fitted into the frame at the same time.

What I'd do differently

I would maybe have pulled a little further back to fit even more in the frame.
