a lot is done in ms paint.
there are websites that you can make comics on so I do some of it there then finish them off in paint.
just type in comic maker and a shit ton will pop up. I make steemit dude mainly on marvels one. a lot of the time I make the base or single objects in generators then after I cut them all up and stick them together with ms paint. quality is lacking a lot because I don't have anything better then ms paint. :/
glad you enjoyed the comic.
