Hate to tell you this (again?) but the depth of field is too great for
this particular object. You have here a bonsai tree (those subminiature
bits of vegatation loved by all and bonsai hobbyists most) with your
face up close to it. I might be exaggerating but do me and yourself a
favor and look at a tree somewhere (not a houseplant) and close one eye
then the other taking note of how much shift there is in the limbs. It
should be only just noticeable, say a few inches at the distance of the
tree if it's about 50 feet away. Well in reality it's always about 2 and
a half inches because of your eye separation :)
However the larger and further the subject object is the less apparent
this is obviously making things get pretty flat after several hundred
feet. Of course I'm just pointing out the basic thing about stereopair
images and I'm no authority either, far from it. Your tree 3D render is
still like the photographs I've taken albeit the foreground of much
larger structures or landscapes. The tree being the subject matter
though  could certainly fair better with less left/right shift. As is it
is very much like looking at a bonsai tree on a desktop.
Please don't think I'm forcing my way on you okay? Like I say I only do
this already in reality and 3D modeling and amatuerishly as can be. Just
hoping to point out some things to you and others who may be wondering
of this sort of thing.
