What are you looking at?
One of the things that makes a 3D scene less real is that the characters are not quite looking where they are supposed to be.    Even in the real world these visual cues can be very subtle,  so we are going to use a stick and a spare camera to make the "looking zone" more realistic.

First,  we make a stick from the Poser cylinder (under Props / Primitives).   Set the Xscale and Zscale to 3% and the Yscale to 1000% (for a start,  we may need more or less later)

Now,  while we have the cylinder selected,  change its parent to the Left Eye of the figure.

Now set the X Rotate of the cylinder to 90 ° and use the X Y and Z trans dials to set the cylinder in the middle of his left eye.    The actual numbers vary from figure to figure (and your measurement base) and depend on the origin of the eye.   If you use inches,  try X about 1.25, Y around 72, and Z=5.   You should probably use the face camera for the easiest way to set this.

The stick is pretty good for aiming, but there is an extra tool we can use. We are going to select the "Dolly Camera" and parent it to the left eye. Set the Roll and Pitch to 0 ° and Yaw to 180 °    Now when we switch the view to the Dolly camera,  we look at the scene from the figures viewpoint.

Now here is a picture of James talking with Jessi and making eye contact,  and here is what he sees thru the dolly camera.

You can keep the cylinder in the scene and just make it not visible in the library palette.   It's handy to have around for scene changes.
