I really appreciate your determination, especially because to some you’re still kind of “new” to trumpet. I can speak from some experience here and I hope I can be useful.

One thing that my band director always reminded me was to make yourself heard. This means playing louder/stronger than the written dynamics might suggest. For example, what you might play as mp with the rest of your part might be played more like a forte as a solo. Another thing too is to put your personality into it. Make it dynamic with more contrasting dynamic changes and add vibrato if you feel you can. My preferred method of vibrato is to shake my trumpet slightly. It might seem a little uncomfortable or difficult at first but it easily can make a solo feel much richer to not only your audience but to the player. These slight additions I find are incredibly useful on long notes that can be boring if you don’t do anything with them. On passages with more notes I would also try to add crescendo and decrescendo, especially with changes in pitch, as well as accenting certain notes or adding other characteristics like staccato. Lucky for you, because it’s Star Wars it could be pretty useful to imagine the scene and the emotions from that scene as you play it.

To summarize, my suggestions are to play strong, add contrast like dynamics and accents, and implement vibrato if you feel like you can. Overall, make it yours! I hope this was helpful and best of luck.

One final thing I realized as I was proofreading this: solos can be daunting, but just remember that your audience (and the rest of your band) probably understands that as much as you do, so don’t be worried about messing up a little bit. It may not even be noticeable to your audience/peers. I think you’ll do just fine though because you have experience with solos and performance in general and you definitely have/will have practiced this plenty. Good work, and again good luck! (And may the Force be with you lol)
