It fell flat.
Super flat. The whole thing went nowhere, by title alone I was able to piece what was going to happen and the "Twist" Or "Climax" just fell through. The hype building to the execution was just bland and monotonous. And then the after effect of the new victim coming in was also played out.
Here's some things I felt could've given it a bit of a psychological oomph;
~There were other portiraits, showing the Artists 'Works' while panning across each one, just show in a quick flash how the event came to be instead of just panning over them.
~Had the door just slammed ominously as she entered the apartment and it cut straight to credits. I feel the scream at the end was really cheesing the whole thing and made it more "lol death" than horrifying.
~Nobody needs to see a murderers apartment. Front door, hallway, art room. I couldn't care less if he had an electric or gas stove. It was only a few seconds but for a first time viewer, those seconds feel much longer than a repeat showing. You got them to click play, show them the nitty gritty off the bat.
~~~Addendum: If you are trying to draw it out and get them hyped up, got with more 'portriats' of the artist's vics. Make it seem like he's been doing it for a real long time. Make him seem like a absolute monster.
Anyway, that's just me, You seem to have some favorable reviews and hey, you got frontpaged. So enjoy it man. Someone saw potential in your stuff so keep up the good work.
