>>3711429I think it's more about exploiting psychology. Generally speaking, alone makes you feel creepy. The unknown makes you feel creepy. Spikes(sharp turns, pins, sudden sound) make you feel creepy. Emptiness make you feel creepy, and so on. Also, just my observation, but when you're alone, if you get paranoid you'd not focus on yourself, but your surroundings- I think that'd be a cherry on top kind of thing. Making the subject of your drawing have less contrast and darker, for example.
