The drawing is great, but you should just jump into Inkscape and do it up right. It’s pretty much as easy as Microsoft paint, you just have to tinker with it and you’ll get it in no time.
And if that fails, just copy/paste the picture without the stickers into Inkscape and make the stickers in Inkscape, so they can actually turn green or disappear! This is a very fun idea, though!
Also could I have the fridge without the stickers
and all the stickers?
