*BUMP!* (didn't know where else to put this)
I knew there were two versions of the Enterprise model, one with a 2D pic of the bridge in the front window, which is a bit too wide and short, and the other for compositing with live-action footage of the bridge set. I knew they differed slightly in height of the ridge around the dome and shape of the window itself, but I never realized until now that in the latter, the side apertures are weirdly distorted. It's like they only dragged up the edges nearest the window, leaving them slanted.
