I was on the phone with tech support while doodling. The sail boat came first--then the mountains. The clouds were the most fun.
This is an old school pencil sketch. I used a 0.5 mm Techniclick II mechanical pencil and a Pentel Clicks Eraser (for the clouds). It was draw on a page of my soft cover Moleskine notebook.
