This is a pencil sketch/drawing on post-it note. I kinda like the post-it notes since I can stick a bunch of them on one single piece of paper for archival instead of keeping a bunch of 9x12 inch drawing paper pages. Downside is that post-it notes are very slick and it's super easy to smudge the graphite all over the place.

Anyways, here's the reference photo: This is me. Would love to be someone's muse-for-a-day.
