Back to the front again and this time I only do the darkest horizon line. To start adding a little flare to the render I added some yellow prismacolor to the groind and reflected it up into the side. If you notice on the door I put some little tree reflection on the horizon, not that you need it but thats where I want my spotlight to hit, so you want to make sure the reflection at the horizon is darkest at that spot, so I went to the back again and added some straight black to make it darker.

Finally chalk!! I start on the backside cuz this is where I usually screw it up. I used orange on the side for warm, leaving my hot spot white and blue on the hood and roof for the cool side.
