Well the video fx and colour washin is what you could call scary mysterious and would work
But the actor is too young looking to be scary - partially shaving his head - part of an eyebrow and sticking his face into mud would give you a better looking psycho nutter kind of look but just too young for close up to be scary
Best cut is about 27 secs in thats good
The matrixy look comes out more amusing and funny than mysterious - and the shooting would maybe be better done in an old derelict building for the backdrops
Its too hard to capture that feel without paying attention to set and the subjects your filming - music is good for the feel
I dont think your bro will go for the headshavin idea though
