Sorry, my friend.
Not only is this tileset NOT from Stargate (and I’ve seen almost every episode, believe you me), but it’s NOT worth a perfect 10.
For your (the uploader’s) sake, I will list each problem, then give you a possible solution for it.

The level was quite small. There were about four or five main rooms on one long, narrow ship, and a little flying around action on the outside. Everything was too one-dimensional.
The solution here is obvious: Make it bigger. Add at least one additional deck to your ship, if not two.
There wasn’t enough ammo. In addition, the fans inside of the ship were a little irritating, and the pipes on the outside even more so. The trigger crates served little purpose, and the Fly Off on top on the ship, in conjecture with the bottomless abyss at the bottom of the level, was very frustrating.
In keeping with the last solution, put some more ammo pickups and sundry in the new rooms you build. In addition, put a carrot or two in. Carrots keep you alive, and to not have even ONE in your level at all is tantamount to a federal offense within this community. Remove the trigger crates, since they do almost nothing.
Remove the Fly Off on the top of the ship, or at least create an MCE Death Pit at the bottom of the level. In case you didn’t know it, the very bottom of Jazz2 levels is NOT an instant death pit. You will hang in place there for the rest of time, and this is an absolute no-no in any level.
Take the interior fans out, please. They’re just plain annoying.

On the converse, your level DID have a decently good song, being the JJ1 Battleships song. Always remember, Duke, that a level’s song is almost as important as the level itself. Atmosphere can be created or ruined with music, so getting a good background track is essential.
It actually earned you points in my review, which otherwise would’ve graded you MUCH more harshly.
The eyecandy of Star Ship Terra, while not terrible, was nonetheless quite underwhelming. Odyssey is such a potential-loaded set. Use it! There are so many impressive levels using this tileset, so take a page from them (although don’t rip them off outright, ‘cause that’d be rather cheap).
In closing, I would like to tip my hat to you, for beginning your legacy here on J2O. Keep chiseling away at your craft, and watch it improve. Lord knows mine has.
Unfortunately, that also means that, since you’re in the thick of the beginner’s doldrums, you’ll get a lot of negative reviews until your levels start turning heads. It’s all right. Hopefully, you’ll improve quickly enough that you won’t have to get used to the sensation.
No download recommendation at this time, but just wait. Time will tell how far Duke can go.
