MS Paint helped me get into Digital Art! I used it for quite a while making silly drawings and pixel art (which are sadly lost to time ) before I found Medibang. I still love it though despite how simple it is.
Anybody from early 2000's draw Club Penguin Penguin and Puffles from there?i made a LOT, and they honestly sucked. I'm not sharing them because I don't have access anymore (insert smirk here) but that's ok with me, that's probably for the best xD
MS paint is what made me realize, "Hey, I can do the draw!" I always liked messing around, making funny stuff, but one time I decided to draw a random Pokémon on it. I randomized and got Chimecho, and after I drew it I was really proud, so then I drew another, and a different thing, and oh look if I do this on my phone I can kinda draw, and ooh what's this free drawing app- so on so forth. I haven't actually played with MS paint in awhile-
