Frozen concept art. Anna was to have magic in early Frozen designs and here it looks like she had power over the Aurora Borealis and is trying to dispel Elsa’s winter storm. I love the contrast between the two sisters in the last picture. We can see Elsa grieving over her sister. It must have killed Anna to stop Elsa’s storm. Just like in the final designs it takes Anna life to show Elsa the era of her ways.
I always wonder if these are actual concept art. Regardless, beautiful work with really interesting character development.
