Some animatics I found to be good reference when creating my own. Mainly to see how they use different angles/distances for cinematic effect.
The dynamic sequence when she's on her broom was really impressive, you definitely get a sense of the camera 'moving' after and around her.
This one has nice exaggerated character movement and expressions which are used to great comedic effect.
The above link is for a deleted scene from Frozen, I actually really like it and feel it'd have been nice to see in the final film. It shows a more light-hearted side of the dynamics of Elsa and Anna's relationship and their personality differences. As the focus is on the dialogue, the camera movement is kept limited with a focus on the character's expressions and gestures.
