If you can't decide what to draw, but you want to draw something. You might have made something like these before. They are easy to do and make good backgrounds for things like computer backgrounds or blog backgrounds. To make one, all you have to do is make a bunch of scribbles, and use your drawing programs effects (if you only have MS paint, you can always just do scribbles). The first picture that I made (to the left), could look like a tunnel with different layers.
Not sure what this one looks like (maybe something with scales?)
And this one has more of a comic book look.
