Preview looks pretty good, and this is looking like a great attraction. I like how this is going, but if you want to improve this, then take some of my advice.
So far this ride is just Mattatt14's set put together well, and most anyone who's played RCT3 for at least a month can do that. Back in the day, when we didn't have fancy sets like this, it took lots of time, to put together something close to Space Mountain. I made a few, and all it was, was a big building, with star walls all over the place. Star walls from Jcats space worx, and star floors. Now I'm hoping you've noticed that the star pattern is very repetitive. Nothing the star cube can't fix up. The star cube is just a cube of stars, that has no background, you can put it anywhere and it'll make it look like the wall or object in front of it has stars. That way you can place those in spots that restart the pattern, and so on, and on the outside of the lift tube. Also SUPPORTS!!! As of now all you are using is the RCT3 supports, and we all know they look very crappy, especially in a space mountain. To get rid of them, go to options, then click the eye ball, and then checkmark the setting that says Show LOD options. Then it'll show bars, go down to the one that says support, and on the right side bar click and drag it all the way down. Draw distance, this will make it invisible, then using steelworx, you can throw in some supports. Keep in mind that Space mountain mainly uses the beams in different configurations, rather then the really big thick supports that are in the set. But it does use a few of the big ones, but not too many.
I'm not saying that you shouldn't use the set, all I'm saying is that lots of other people just did what you did and made a video, and if you want your video to stand out, then you gotta make yours a bit differet, have more stuff. Again, i'm not trying to be mean, constructive criticism always helps
