This is a good subject...a great subject, really. However, it could use a different angle to eliminate the background clutter, and perhaps a different time of day to lessen the shadows. Shoot this again and post the results. Good luck.
I like the patterns of lights and darks on this object. The background looks a little washed out, though. Maybe a different angle would have been easier to balance.
Ah this object I know too well. We had the same seat on our old hay shedder, pulled by our horse. The fact that there is moss growing, means the air in your area is rather 'clean'. I think it's a bit overlightened. I'll rate it a 6.
I would have liked this much better if the seat had been in the shade more and the background wasn't so bright. The contrast between the moss and the rust could have been better emphasized.
This is a nice idea, good composition. I would have tried to do several things: 1. cut down on the dof so the objects in the back ground weren't in focus, 2. taken this at a different time of day, looks like there is too much contrast for the camera to handle.
