For me, visualization is not about 'beautiful' drawings, but whether or not a drawing helps people to understand, share and remember. Information overload is all around us. Talking or writing is no longer enough. It's only logical to make people SEE what they are talking about, to make it stick.
I work with simple shapes and strong lines. What is most important for me, is to capture those key elements that evoke a sense of recognition. In my previous career I worked in content, communications and consultancy. That's how I learned to really listen, process information fast and to capture the essence of a conversation.
