Thanks for your comments!
@JamesRuddick and asian.monkey: Yes, that miserable UV texture isn’t working in that render… I think I got it now, though.
@asian.monkey: By painterly, I mean I want the image to have a painted feeling. Does that make sense? Also, my original concept didn’t have any clouds, but I think you are right about putting some in.
@MCNano117: Ya, I’ve worked a little on that car. Good thoughts, though. I shall see about putting some in.
Also, I added some stuff, and I worked in the compositor a little more, and I think I’m getting closer to what I want.
