Demonic character

The plot for the production is still in process but the main point of the introduction is a friend being possessed by a demon, showing black eyes, black or red blood and I will experiment with my own voice on Audacity to create demonic voices whenever my character speaks.

Although I do want to tweak several details, around the eyes will be a natural skin red to show tiredness or illness to add more of a realism to the video. This character will use black or red food colouring to create a blood effect- red for realism OR black because demons aren't exactly human.

I have a few old pictures from years ago that also demonstrate the effect we wish to create:
