I used to do picture books in the 80s of fantasy stuff with other kids.
90s was more hand written on line paper short stories and OC raw sketches. I eventually had them typed up onto a floppy disk. And printed them off to share in small cardstock folder with metal pinch prongs. Which Canadians call a duatang. Still have one copy of each and it on a floppy. I also did local school anthologies and contests. And newspaper ads for local charities.
Early 2000s I was in college so did half tradtional written stories + mixed media art. And Digital. But also took my coding skills from the 80s + 90s courses and put my art online my first domain site. And still have been online, with a domain since.
In 2012 was part of the local comic cons art dept.
Since 2019 onward I've had short stories printed in books from local authors and done in person - huge event art galleries in Toronto too.
So its been a decades I guess.
