Hi Kirk, nice panos, I like the third one where one can see the shadow of NN making sunbath.
For positioning you can use parallax, mean the releative position of the small vertical elements over the main door and relative position of a near tree over a distant one. One can make two prints extracted from previous pano at say 90¬? yaw apart that checking those on the field.
Seems that you managed to have a pretty close position
