Scrawled some thoughts with the scene vision.
1: Bugs from the movie are constantly bombing a huge and high wall.
2: Dropship flies over the area that is being bombed by the beetles or even by something that is not even shown in the scene. Heavy rain, thunder, lightning.
3: Forest fairies waging war on insects. As ammunition, they use magical balls made by elves from Lapland Rosebay flowers.
Distancing itself from the original vision of the idea, it only made one understand whether I wanted to go that far.
Will go with 2nd vision it has some flexibility as the entire scene is dynamic. Hence, the plan is to define / produce the minimum required content to bring the scene to life and then add more if there is time left before the deadline.
