   Thanks, also for the reference pic, as it served to polish some details,
including some of the ones you mention later.

   For the color variation I used directly colors picked from the pic you
linked, but they don't look so natural... perhaps because the sunlight color
is somewhat yellowish.

   I think the density of the distribution is now better, but that was a nice
side effect of trying to implement a suggestion from Darren... ;)
