Very strong message in this one, and in my opinion a good effective storytelling technique as well. Very clear, instantly calling upon an emotion, and I think most of the audience should quickly understand what it’s about.
Regarding lighting, I think the mood of a classroom is conveyed quite nicely and the lighting helps to strengthen this feeling. My attention was drawn a bit more on the colors than lights tbh… there’s a good harmony in the colors used in this scene.
