What are the guidelines for the tileset sample maps?

[Strajder]

I've been searching for guidelines on how should a tileset sample map look like, but couldn't find them. I'd like to create one for my custom Draenor tileset. Nothing special, just a bit of terrain to showcase different tiles and a few doodads. Would that be ok, or should I be more elaborate?

Thanks for the guide, but what I meant was are there any rules on what should sample maps that act as tileset showcases look like.
