May the Fourth
I'm not a huge Star Wars fan, but I love the challenge of painting or sketching something for May the Fourth Be With You day each year, and seeing the progress in my art.
This year I surprised myself with this sketch, and I can honestly say I have NEVER sketched C-3PO or R2-D2 before - and they're busy characters! That's the main reason I decided to sketch upside down - so that I was only looking at the shapes and not letting my mind get in the way by thinking of arms and legs, etc. I really recommend having a go at drawing this way!
