My analysis of the Croft photo shows Connally's much of right shoulder was to the left of Kennedy's midline. See in the photo how much larger Jackie's head is than Kennedy's, and that Connally's head is a little bigger than JFK? That's because they're closer in space to Croft than is the President. The model reflects the position of Kennedy and Connally in terms of where their heads are. The head positions in the model also relate perfectly to where their heads are recorded in the Altgens photo on Houston.
What I would like to see is how your images look from the vantage point of Zapruder. One sees in the Zfilm that the heads of JFK and Roy Kellerman seem to align in a straight line parallel to the car side and JBC's is slightly inside that line (see zframe 189 as well as 193, both of which are reasonably clear).
Also, you have JFK's elbow quite far forward which seems unnatural. I don't see the upper arm pointing that much forward in the zfilm. The elbow is farther back. The way you have it, his elbow is about the same elevation as his right shoulder. The shoulder is much higher as seen in z193. This necessarily puts the side of JFK's torso farther inside than you have him.
You also seem to have JBC's jump seat quite far to the left. What is the distance you are using between the edge of the jump seat and the right inside door panel?
My model for Z195 shows Connally inboard of Kennedy. Do you have any of your own 3D work of comparable quality?
You do great 3D images, Jerry. I wish I had the time to learn how to do it as well as you do.
You're not referring to your "FAIL" use of muddy frames from the 1963 SS reenactment film? They were so muddy, you thought the car was a convertible five-feet shorter than the model seen in the SS film.
It doesn't matter what the length of the car is. What matters is where JFK is positioned.
