Hi katanalevy, thank you for you feedbacks! They are really appreciated!
Most of the inspiration came after playing Bloodborne, the assets will be replaced if I have to release the game, I can iterate more (gameplay, feeling, etc.) using assets taken from the store.
The fog was really a performance hit, I optimized a but the shader, the fog is a less bit pretty but performance gained form 30fps to 1-2fps.
For the sound I admit that I had to put more effort, one of the aspect of many of my demos.
I really liked the Bloodborne trailer and I was too temped to try it as a prototype trailer, I admit that probably I will have to change it or do differently in the next demo trailer.
