I noticed a couple chalk marks that look like they were hand drawn. If that's true, then you might find this page interesting.

It describes making a circuit but the layout is almost identical to a drag and so the same ideas can be used. You'd just draw chalk marks instead of filling in with dirt or grass. The point today, however, is that you can take advantage of psp's shape tool to help spiff up your track's lines and textures. If anything is not clear, please just ask.
