I did this when I was about 14 years old. I've always had a fascination with eyeball close ups. I saw the booklet for Tool's Opiate album and had to try drawing it. This is actually my 2nd go at it. When I showed the 1st one to my art teacher he introduced me to pencils with w/ varied lead densities and this is the result.
I love it.
I remember when I looked at that cd, I got scarred for life, but I made an anime version of this... it sucked. hahahahaha. I love Tool's eyes...
I think I owned that cd a good day or 2 before I realized that's what the pic. was. I got so pleased at art in general that I had to give it a go myself.
