Second page sketch Idea

 This is my sketch for the second page.

Here are some of my first ideas:
– They are trying to protect the world by fighting against their own elements.
– Some environmental monsters appear and attack them.

For the scene, I drew three parts:
– In the first part, a monster comes out from under the ground.
– In the second part, the boy with the air power watches the event from a different place in the world.
– In the third part, the father also sees what is happening, from another location.
