Keep up the emotional parts in a very high priority. When the fearless boys went inside a such old house like in resident evil you can push up the suspense with some wind sounds or thunder in a far distance, maybe a lonesome wolf is howling, some flickering lights, maybe the furniture should not look so clean?
In my opinion the emotional is the main thrilling part of the whole scene.
Is it possible to spend the characters some more animations?
The boy should react when the windows break (maybe he looks very irritated in the two directions) and he should take a few steps back when the chandelier comes down.
Anyway, I like the atmosphere of the shown video very much.
