I'm always intrigued by artists/illustrators/makers methods, could watch Bob Ross all day.
I'll show you mine if you show me yours!
1. Sketch out in pencil ( Istarted with Phileas Fogg as that was the main focus of the illustration ).
2. Work over in various thickness pens ( Inked Fogg first so I didn't rub away the pencil
with my hand while working on the left side of the pad ).
3. Sketch out background in pencil then ink.
4. Scan and then paint in Photoshop.
