Designing for Happiness sketch notes-example of great note taking, yet fun too!
Absolutely Fantastic style in this sketchbook. Not sure who the artist is. There's a link below...however it's a Chinese site, so I'm confused about whether or not this is an artist showcasing their work, or if this is a Chinese Pinterest style board/blog.
