This was awesome, I'm so glad SE is getting some more recognition, even if it's peripherally!
The one thing I wish Overview had had which SE has is proper auto-exposure. SE's auto-exposure is one of the things that differentiates its visuals from so many other space sims'. In real life, space is full of stark contrasts; if there's bright starlight in your field of view, or the field of view of your camera, you're not going to be able to see the Milky Way in the background, or nebulas, or other stars. That's one of the things that makes photos of Earth and other planets so uniquely beautiful!
Overview obviously didn't have this, which was a shame as it meant one of SE's strongest features - how dang realistic it looks - was missing.
In any case though, I thought it was really well done - I was surprised just how good the production values were actually.
