with just a small amout of the belt showing it doesn't seem long to me. I like the idea but I think the belt could have been displayed better to show off the length.
I like the contrast of the belt on the faded jeans. I'm not sure about the green in the background as I find it a little distracting, but good closeup.
Nice macro. I think it might be more effective if you couldn't see the button of the jeans - I find that a tad distracting. Maybe shoot from an unusual angte to create a bit more interesting perspective. I'd like to see these being worn by a person. The clarity and focus are well executed. I hope you find this helpful.
