I think I got cool inspiration or pixel tip: You should use 2 colors and draw completely random stuff like doodle. In Atari timeline, many sprites and drawings looks awkward, yet our imagination increases drastically upon...

...visualizing what it is. For certain people, there are certain colors that calls 'perfect paper and ink' like mine is green and black. This sprite could be a claw or a bulldozer or abandon machine. Its great to imagine it like Toy-Catch minigame, Abandon Warehouse Spooky games, and more! Imagination is the power!

This incredibly simple sprite can be big things.
