Hi, I am also a beginner so I can only tell you my opinion which may or may not be correct.
I liked it overall, but I am not sure about the music at the start. I think the faintest sound of crying, slowly getting louder as the men approach the stairs would have been stronger. For me, that would have told the story of them looking for somebody in need of help, and when she turned crazy and ran at them, the shock would have been even greater. The music sort of tells you that she's a wrongun
I really liked that scene by the way, it was my favourite in the film.
The only criticism I have is that this edit didn't really tell much of a story, but I am guessing that is because it wasn't meant to be watched without the rest of the film?
Good work though!
