It’s good to start by using whatever pens. I use tools that make marks that I like; tools that work with my process.
If I’ve mastered anything it’s by not believing I’ve mastered anything. Draw Draw Draw. I look a lot at dead artists. For mark making, Hokusai is a favorite of mine. He’s a well known dude. His marks are great for describing forms without directly leaning on illusion and the marks themselves are usually beautiful. Plus he’s long dead so I don’t feel bad about studying him.
…and thanks for the love.
