A few months ago I put together a shuttlebay interior for Riley's old USS Phobos object. It began life as a general sci-fi hangarbay (wonderfully designed by another artist), so I had to kitbash and retcon it heavily to make it fit and look reasonable for this application. It features a control room (probably main engineering) and a rotating lift, which is used to re-orient the shuttle after each trip. The size and shape restrictions of the ship's empty cavity didn't allow me to easily re-scale everything, and so you can see that the steps and rails are a bit under-scaled; but I think it's passable.
I fussed with the lighting for many weeks, because at that time I had almost no experience lighting interior scenes. These are some of the better renders.
