I'm trying to decide if I want to keep the grid lines or not. I've always like the idea of them, even if their implementation has always been flawed. Given that it has windows on the port side and other details missing from the original studio model, I'm happy with the idea that this is an interpretation of the Enterprise
and not necessarily a perfect replica of one of the shooting models.
If I do keep the lines, at the very least I'll remove them where they trace over the triangular hatches on the underside and the rectangular patches over engineering. I also think the space around the ventral dome should be free of radial lines up to the first circular grid.
I'm also thinking of shifting the turbolift so that it lines up with the Bridge interior detail.
