Thanks buddies! I really appreciate your honest opinions and your tips!!!
Yes, if I watch the footage again and again I can just agree that I should have thought about more psychological effects, other cuts.
nhzoso: Yes, I added the sounds after video editing and cutting. Generally it`s a low "creepy" pad with a few light crescendos. Additionally I threw in some strings to build tension, this shout-like sound and the whistling person washing his/her hands.
More on the way, these days I`m getting outside...not just gigging, also filming.
