It's very dark and it doesn't appear as if you can actually see much of the ground.  But, with the figure on the far right, it appears to me that there is indeed a ground shadow.  It's just very broken up because of the groundplane effects.  But, it is there, to me.  Of course, that may just be my eyes playing tricks on me because I have a lot of contrast between that pic and the white background border of my screen.  I'll open it up in a image editor and check it at full screen so my eyes don't "wash out" the details due to a bright border around such a dark picture.
