These are design studies for the businessman's planet in The Little Prince. I thought I'd go for a more interesting shape than a mere sphere and I drew inspiration from asteroids.
The thumbs are done in a graphite technique taught to me by my mentor, Patrick Hanenberger where you lay down graphite powder in a wash and erase out to find shapes. The last image is just of some rough thumbnail studies done with warm copic gray markers in 3 values.
