I only want to talk about image 1 the others are good but 1 for me is great I love it the front reminds me of the lead character in the cartoon animation Robots. It has a face and although old and rusty is still sort of smiling for the camera. Love the nostalgia in it. I know I say this a lot but maybe a B&W or even a sepia copy might be good. But saying that I love the colour of this image.
