One last render before bedtime. Increased the light to about 350 % and made shadows softer. Moved the camera back a little so you can see where the world zero is on the sand where it meets the concrete surface.

I think the sand is looking pretty good accept for the dark line needs to be  several feet lower. I by the way am using feet as my unit of measure.

Just can't figure out what setting to change to get the dark line to move lower. Also would like the dark line to be more subtle if that is possible.
