This sketch was one in my small moleskine with the wonderful medium of graphite.
Graphite tends to smudge as the small particles sit on top of the tooth of the paper.
The smoother the paper, the less it sticks. Fixative is necessary if you want to keep the integrity of your drawing, or in my case I just scanned it.
This drawing was done with a dollar store pen set that had all the colors of the rainbow. I called it 'blockhead' for ironic reasons, maybeI don't actually know why. It's how my brain works I guess.
It just goes to show you that a sketch can be anything, especially because this one is just fun and brings a smile to my face when I see it.
