I see two things which are probably the cause of the
inconsistencies you are observing.

First, there appear to be at least three light sources
in various places across the image. This would have the
effect of eliminating shadows in some areas and in others
causing shadows to appear to be in the 'wrong' spot.
Human vision is used to only one light source (sun).

Second, the image is in compressed .jpg format. This is
a lossy format that reduces image information in exchange
for a reduction in file size. This has the effect of
creating compression artifacts, especially around edges
and in areas of low contrast. This could be what makes
the man appear to have a "cut & paste" look to him.

Now, what surprises me most about the image is that
people actually went INSIDE this cavity!!!! That
must have been an erie feeling to know you are inside
this cavern hundreds of feet underground that was just
recently formed by a nuclear bomb. A definate E-ticket
thrill.
