Draw whatever you want, anime, memes, shitposts, the entirety of Mario world 1 level 1 in a mural, just don't draw over other people's stuff and have fun
also recommended method us "add pic" then trace and draw over that, once you have the outline move the pic away, color the outline and then erase the pic
listen up you donks; I found a site that lets anybody draw on it, but without paying the max length is 14 days; in 14 days we can see what the community made and I will make a post with the link every day until it ends; try not to harass or erase any other people's works
