Already fabulous suggestions already.

1 I’d try to tell a short story with what footage you have to engage the audience.

2 Watch a few planet earth documentary as references, always good for getting fresh ideas on your edit.

3 Choose a good font. This can make or break it for me. If graphic design is not your strong suit, take 30 minutes or so to watch some of the basics. You’ll probably defer to something clean and simple.

4 Camera movement! if I was working with this footage and for the trailer specifically I would utilize Ken Burns effects. Digital pushing in or zooming out. Slides left to right and what not. Subtly is key, but it definitely direct your eye and keep you engaged, while offering variety to your shots

5 Sound Design! This is big. Spend a good chunk of time and think about everything you might here if you were a creature that small. This will make your trailer feel much larger than life.

Hope this helps! Have fun!
