If you look at the comparison video i posted the original 2004 emperor hologram lowers at that exact same point. I had to track the original to match up the overlayed mask so the movement needed to stay the same. The problem with the hologram beings semi-transparent is that the original background shows through, so if i tried to erase the slight drop of the hologram, the background behind the original face would look like it's moving upwards. But i might see if i can do something about it. If not then it will just have to stay as it is

I wouldn't even worry about it. It looks perfect the way it is. I didn't even notice the drop until I read that. It's all part of the hologram's fuzziness.
