At first glance one thinks the model should be placed further down the walkway to better demonstrate the concept in leading lines that the lines should lead to a payoff.
In this case it looks like the lines lead past the main subject until the viewer realizes that the lines are leading EXACTLY where the photographer intended. lol!!!! ;) ;)
An excellent example of leading lines, especially how you've combined it with rule of thirds placement of your model.
It does not have over-the-top HDR processing so popular at DPC so will not score as high as many others but is one of the best, most intriguing examples of leading lines in the challenge.
For this particular challenge I'd have placed your model further along the bridge. As it is, her placement is interrupting the lines created by the woodwork.
The quality of this image is terrific. I didn't think the lines were particularly leading until I decided to follow them, and they led me to her hips. So I guess, yeah, they are leading.
