From the ink only sketchbook : Robots. They’re the easiest thing to draw when using a pen.

I got this sketchbook that has perfect paper for my great fountain pen.
I decided to try and draw only in ink in that book. Don’t know if it’s going to last, we’ll see I guess.
It’s a good exercise : you have to live with the first draft. I have to stop and think before I put pencil (pen in this case) to paper, not something I do naturally.
