I think you know what to do. Be sure your sprite is ORIGINAL, which means it can't be a recolored, stolen, or any sprite that wasn't originally made by you. Also, it can't be a PNG from the internet, unless it's as a joke. Bitmaps can be more time-consuming than vectors, but I'll still take them.
All Stickmen are easy... Except for the part where you have to extract the sprite from the backdrop.
