3rd time lucky

I'd had an idea about balls bouncing about with their shadows giving them their position within a 3d piece. After tearing up a few pieces of paper, I'm ashamed to say I gave up. What has happened to my tech drawing skills, I thought they were with me forever....

First I applied the shadows on, and then I added the foreground

 It's still not stitched down but I am pleased with the effect of this very simple piece. So tomorrow I might get round to quilting.....
