My Notesureman was created 'on accident' in a way. I went to see the latest spiderverse movie with my family, and was very impressed with the style of animation and artwork used in it. One of the characters in it was called "Spot", and he looked like this white empty being - devoid of any visual features, but very impactful nonetheless.
A few days later, I doodled in my sketchbook and drew a featureless figure. For some reason, the figure looked like it was not sure of where it was going. It resembled the Spot quite a bit, of course. But was even more simplistic and weird looking. It was as if the little drawn figure was questioning everything around.
I drew a bunch of question marks around it along with some bubbles, and decided to make the figure my own by giving him a name - Notsureman. Since then, The Notsureman appears in my sketches off and on, to either comment or make me ask questions about what bothers me.
I am a happy owner of my own alter-ego. He never judges. He simply asks questions.
