i dont really understand the lyrics because that is not my language but i did watch the whole video and i liked how you developed the character, starting slower and giving it more strenght with the music...
correct me if i'm wrong but the other girl gives a sense of duality to the story telling, i loved the scene with the water followed with the fire, it tells how the girls are opossites but at the same time one takes care of the other... i liked that duality
the initial idea was to film everything with one girl in white and black (it was too complicated and we could not do some stuff so it changed :) ) so you are pretty close to it. Understanding the lyrics would give a bit different perspective but yes it is duality and kinda a inner struggle.
Lyrics are form an old poem, with mother saying to Anča to stay at home and not go to the dance. She will be fine at home. It escalates to a bit of a tragic event (not really explained why in the lyrics :) ). so it could be 2 scenarios. where she does not listen and goes, or the end scene where she decides to listen and stay home.
