The colors are expressing mood, the color black is associated with evil and darkness so it gives this picture an eerie feel. The lines in the way it moves straight and the scream guy is wavy which gives depth to the picture. The other people in the background don't really have a face so it seems mysterious why they are the, but if you look closely the way his foot is going is towards the scream guy, which makes you wonder why he is screaming. His face is also pale and misshapen and that also gives a creepy feel to it.
