The best Scratch tutorials to teach you how to make the things floating around in your head a 2d reality!
My personal tips:
Don't JUST draw what's in your head. Sure, if you want to try to draw it, go ahead. But, the best way to learn is to draw a little bit of everything, and to try a whole bunch of ways to draw it. That way, the things you really want to draw, will come out that much better!
