Love the work Donny!
I am curious - in the TMP version, is there a reason you think the ridges stop part way up? If the ridges along the two sides go up all the way through the ceiling, why not the ridges above the screen?
For the TWOK version - you did an amazing job making the design work, but it just doesn’t feel like that is an actual design. Based on the picture with Chekov it seems like they intended for that ridge piece to still be there. The framing of the scene with Preston for the most part keeps the part above the screen just out of frame. Perhaps it broke at one point or warped to the point it wouldn’t stay in place and they just made do. I know the Chekov scene is a deleted scene and therefore not cannon. But it would be like kind of modeling the TWOK bridge with a damaged viewscreen frame because that’s how it appeared on screen. Or modeling the engine room with the wrinkles in the perspective picture of the vertical intermix chamber. Stuff breaks and the show must go on.
