I love this! What an excellent subject for leading lines. I love the look of this with the pastel blues in the sky, and I'm always a huge fan of the beautiful effect of fog in photos. This is definitely one of my top 2 favorites in this challenge. 10
I am not sure whether there is an unambigious definition of leading lines, but in my book, they should be a line or several lines that lead the viewer's eye towards the main subject of the picture. I think that's not the case in this picture. Your pic uses a vanishing point rather than leading lines.
Very nice symmetric shot, I think the fog establishing the vanishing point really gives interes to this photo. The detail and sharpness is good, like the yellow on the centerline its the perfect color to give a foggy day feel.
