One of the sketch pages from my Dare to Draw Badly project, which can be seen at http://daretodrawbadly.tumblr.com
If you want to help fund this project, I've got a Kickstarter going to help cover the supplies I'm already starting to burn through: http://www.kickstarter.com/projects/950095344/dare-to-draw-badly
Drawn from life, using a replica skull I bought from Skullery last year: http://www.etsy.com/shop/skullery
