I'd have a hard time deciding how to fussy cut this fabric. No matter how you cut it you end up chopping off someone's head or behind. So, I'd buy extra fabric first! That way you can get a "whole" scene to work with. I wouldn't be concerned if what you end up with after fussy cutting is a square, or a rectangle, or free form. You can always add a grassy or woody fabric to make them all the same size.
