I love it. I do think that I prefered it without the shot of the lightsaber splitting because it was not an action that was done out of dark intentions. If anything it was the consequence of not giving in to the darkness.
Also, I would recommend layering in Luke’s voice saying “Who are you?” to further reinforce the dark lineage storyline. Another interesting line you could play with is “Something inside has alway been there. But now its awake”.
