Lol; i've mentally created my trailer, scene by scene, synced to this music:
A massive cornerstone of my comic is showcasing the fictional world the story is situated in: A fantasy world, with different "nations", different cities, with different people and species, all participating in different cultures and experiencing all of the positives and negatives that comes with the nature of their coexistence.
If you want a rough outline of the trailer, it's just a series of shots showing various locations across the world: cities and towns, caves and dungeons, ancient ruins, and natural scenery. In the first bridge (the part with the solo violin), the 4 main protagonists are given their own title card, intro animation, you know.
EDIT: Oh, the comic itself.
