Here is the new Alderaan explosion
As long as you are happy, all if good!
But for me, the two shots look completely different in style. It doesn’t work.
I like the second (new) shot a lot, so why not also replace the first one?
So the reasoning behind splitting the shot in two, is that the first part is almost like a tracking shot from the death star ‘laser’ (Dr. Evil voice) firing up and then firing on Alderaan and the initial explosion - the second shot is the view from elsewhere in the galaxy/neighboring planets. The second shot doesn’t quite work without the first tracking/establishing shot.
