I got Mario Paint for Christmas last year from an awesome friend of mine. Though back when I was 6-7 this game was one of my favourites on my favourite console the SNES (next to Yoshi's Island).
I can safely say it was my first step into digital art and even animation x)

I got bored and started to see how far I could push the game now that I was a bit more art savvy and could actually draw with a mouse.
I eventually gave up and started drawing cartoons instead.

Here's one of Screwball and  shenanigans who I was talking to at the time about SNES games and stuff :)

As a bonus, here's another masterpeice done on MP
