This being hacker news I was hoping he'd talk about his gear a bit. Maybe we could even help him out a bit since he wrote that he's still figuring it out. :-D
Agreed. But, I'd give 10:1 that he's using an iPad Pro + Pencil. Got one a few months ago, have never drawn anything meaningful in my life, but the tools are so good that I wanted to start.
Indeed. I would have been very interested to know more.
