I think the road is too big a surface. It should probably contain a sidewalk on the camera end or something. But maybe it will look better with road lines and texture. I would put some perspective on the lines as you suggest.

Edit, when I posted first, the last image didn't load properly. This one lookds much nicer already! Yes, I feel that the road llines should follow the "vanishing point lines" just like everything else in your drawings. Including the pavement edge on the left.
