Here are a couple more considerably older sketches I did years ago in high school.

My Thoughts Have Turned on Me
Here is another sketch I completed during my junior year of high school in 2007. Quite a bit of proportion issues going on in this one but I still quite like it.
This one comes with a poem.
Through sickly hues of my creation

My dreams have found a new fixation
Upon my own annihilation
My thoughts have turned on me.

The Machine
This is the result of boredom in the classroom of my junior year in high school (2007.) Drawing on myself in such a fashion is an exercise I practice from time to time. This particular version was started with sharpies, then finished in pen.
