|Hi from the Critique Club!
I totally understand what drew you to this. There are lovely rich textures in there, with the metal links contrasting with the texture of the wood.
The eye is led into the image by that round bolt(?) on the left and up to the top middle of the picture. It then follows the links down and out of the image at bottom left. The eye naturally, though, by-passes the area in the middle.
The focus seems a little soft on the links at top right - a smaller aperture would have overcome that.
The contrast here, although fine for a normal study, is not quite high enough for this challenge. Perhaps the lighting that day was a little flat? I would be very tempted to go back a re-shoot with different lighting conditions. Or perhaps try some post processing techniques - Channel mixer, dodging and burning, gradients..etc to try and draw out its full potential?
