Technical: Most all images submitted fit the challenge. This fits well. Exposure composition focus lighting all good, I like the fact that the zip tie almost seems to glow.
Personal: Well done shot, fits the theme well, it's obvious this is a lock of some sort, but I find myself wanting to see more of what's outside the frame to get a better understanding of what exactly I'm looking at.
Really beatiful. I´m not sure that it meets the challenge 100%. But, I really like the colours of this picture. I think the use of soft focus was a interesting choice. Definitely, I like this picture. 8
