Thanks for considering it. As for guidance on an SF scene, I'd focus on "the less right angles the better", and increased variability by using modular pieces. Rather than TNG, I was thinking more of elliptical curves, bows and arcs. Easy on the greebles, though a few would be a nice touch. There isn't really an official SF source I can point to, it's more the SF look I would like to see, rather than what's already out there.

The recent set "the lookout" is somewhere on the right track;

While I like it, something like this could still be given a more subtle, clean look. The basic design, with curved thin columns, is a great one.

As for what's offered now, if you build a quality product at a reasonable price, I think it'll sell, regardless of what else is out there.

The strong do as they can while the weak do as they must.
