Aw man, I remember watching this movie ages ago.
The rendering on the characters looks great, the tonal values make them really pop, and your colours work together well! Good job!
In terms of rendering on the characters and the statue, they look fantastic!
I'd say maybe one way you could improve on this piece is by blurring the background elements to give it more depth because looking at it, it's hard to know where to look at first, or where to guide the eye around.
I see you painted the green hills/mountains in the background, another thing you could try is painting them with a blue wash to push them more into the background; In real life things in the distance are also hazy and blueish.
Maybe another way to improve this is by bringing some of the characters forward more towards the "camera" so we as viewers can have a better look at them or create more focal points in the drawing, cause most of them are at a similar distance further away. Compostion can be a tricky thing to get a grasp of, but you're on your way, good job on this piece, and hope I helped at least a little! ^^
