@R-Fey-Realme This is looking great!
I have some compositional thoughts for you!
The giant is taking up the bottom half of the piece. To some degree it takes up almost two-thirds of the piece. Which creates a little bit of imbalance, which could be why I feel my eyes drawn MORE towards the giant, rather than the goal of the kids being the focal point.

You can see if I remove the giant, I'm much more interested in the kids.
The other thing that I'm not entirely sure about, is that the kids are facing away from the camera. If you want more rienforcement to the kids, you probably should show their faces more. Maybe the angle is flipped. They're point towards us the view, camera is view towards the top, maybe 7-8 feet above them, and then below their feet is the giant. This does conceal the very interesting mountain in the background, so don't consider this if that's not what you want to do.
Maybe the giant isn't dead, maybe it's a statue of a person that's collapsed. You could easily remove the big arm which also takes up a lot of space.
OR
Bring the kids down to the middle plane of the composition, and frame the giant is darkness, but decorate his clothes and his face in a much more interesting way. So the piece is balance with "Interesting adventure top" "Interesting crushed victory at the bottom. If that makes sense. If it doesn't I can doodle something for you.
