Nice image I like your title with the rails and cross members fits well nicely done. However there seems to be a distinct pink hue to the image I don't know if thats what you intented, if not your wb is slightly off.
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.
