Practice with back poses and thumbnailing, which I'm told is mapping out a smaller version of the image to get the big picture details squared away.
Gabby was walking through a forest one day, an odd thing for her to be doing as her absurd normal height causes her and low-hanging branches to get into several fights, when she happened upon a small city of sorts, nearly stepping on it. She thought it was just a discarded model city, albeit an odd place to put one, but a much closer look revealed it to have tiny citizens wandering around, a majority of them stopping and looking up at her. With only a couple of words, she raced off, returning an hour or so later with a shovel. She dug the city out, causing a lot of panic for those curious, and carried it back home with her. A tough feat indeed, given all the problems that arose from simply trying to get it to her room.
