Step 1 - Draw a large circle for his Chibi head. Then box in his chest and draw stick legs and hands. ovals for the feet and hands and a curve for the sword.
Step 2 -
Use the airbrush to paint him in. His ash blonde hair and his black overcoat and shoes.
Step 3 - You can use any background color you like. If you prefer a contrast,use orange. I've used a green to match it with dark grey shadows.
