Here follows some progression shots of drawing this concept on A3 size paper. The first rough sketch in pencil I pretty much nailed that moment, just as it's started to explode with the eyeballs popping out of the skull like Olives.
If you are trying to draw this kind of horror art, I would recommend you do some rough sketches beforehand to get the idea right in your head and the placement of the design. For me, I knew early on that the skull had to be directly in the centre of the paper with everything flowing from that source image.
