Nice! I like the way you've displayed the ship with the figures from the show.
I have 3 DST ships (1701, -D, -E) as well as most of the AA/DST TNG and DS9 figures, and maybe half of the TOS figures I need.
I also collect the HotWheels Trek ships, and think I have all of them (I won the super awesome deluxe special edition of Star Trek scene it on another forum, and it came packed with 6 or 8 of those ships, most I think weren't available separately, like the NX-01 and Narada, Battle Damaged Enterprise A (I have the extras for sale, check my sig).
I have all the figures on one shelf, standing pretty close to each other, and since the 7" figures sometimes have loose-ish knees or ankles, of course one fell down and knocked almost everybody over, and I haven't taken the time to stand them up again (it's happened several times)
So what are those stands you are using? Do they keep them from falling over?
