The challenge was in the textures of smooth leather and velours-like suede. I sketched it with pencil lightly first because I wanted some exactness. Most is done with a humble ball point pen, however, for the suede parts, I cross-hatched lightly in pen then went over it with a Prismacolor black pencil. I used colored pencils for the beige interior as well. The shadow is in watercolor.
The background will get a watercolor treatment.
I might get wild...now there's a pleasant thought.
