Secondly, in the opening shot of Echo Base where Han rides up to the cavernous entrance on the Tauntaun, I don't recall if it was an SE addition or an Ady addition, but the Rebel Soldier standing straight up and holding the gizmo near the turret - well, he kinda looks mannequin-like. I think it's his "stillness" and his pose. I know he's "moving" in the shot, but in the span of the footage at a glance, he kind of looks like a cardboard cutout.

Every other element in that shot looks perfect. The guy with the cannon control box just isn't meshing as well.

The guy with the macrobinoculars is an Ady add from later on in the movie. I think that the average viewer won't notice his not moving since they'll be watching Han entering the base in the background. Our experienced eyes are drawn to that which is new since we've seen it so many times. And if he did the exact movements that he does later on in the movie, it would be more obvious of a cut and paste job. I imagine that he is just very vigilant!
