When I was around 8 I took drawing lessons from this elderly man . Often the students would have to draw a cartoon character from a reference photo . Whenever he would draw or fix something for me , his hand always shook so the lines were usually very squiggly . I ' m guessing it was probably because of old age , but 8 year old me didn ' t know that and I thought he was doing it on purpose . So I would copy his ' technique ' and ended up drawing many squiggly cartoon characters like squiggly Astro Boy or squiggly Pikachu or Squiggly Tom Jerry . Pretty much every character looked like they were underwater . I honestly don ' t know if he had any reaction towards what I did because I legitimately thought I producing some top notch art right there .
