Obi-Wan Kenobi as a young padawan

I loved these books as a kid. Drawing the above picture of young Obi-Wan felt like... well, kind of like fulfilling a promise to my younger self. I'm re-reading these, and though I can see now that the writing isn't very good, there's still a spark of magic there.
