Death Scream Bloody Gore(ish) Drawing

Friend Told me to draw Scream Bloody Gore So I thought i'd add a lil extra by adding NOT Man from Anthrax, Vic RattleHead from Megadeth, and Eddy The Head from Iron Maiden. I recently completed, took quite long to finish, also thats skull guy looks retarded i kinda gave up trying to make it look perfect, and the hardest part of drawing was doing the fucking stupid shit on top of the chair took so long so just did anything for it. kinda new at shading so shading is decent, but yea, hope yous like it. Done during class periods so thats why it has a Folding crease, from putting it in and out of binder, teachers didnt mind just thought it was cool
Looks much better in person, you can actually see the shadings good, but here u cant since flash was to bright, but no flash was to dark.
