Magazine planning images for front cover/ contents

This image I drew could possibly be used for my music mag as I will be taking a cartoon approach to add a twist to my magazine. So how does this relate to rock? I deliberately drew him with a creepy smile to express a psychotic emotion on his face. this links with rock on an emotional lever as it is seen to have such emotion connotations as Anger, Rage, Frustration and Psychotics.
However, Those emotional are only really seen in the world of Heavy Metal.
In the world of 'normal' rock, All emotions can apply, Even happiness and sadness can apply as demonstrated through songs written by Three Days Grace.
