Help: How to make a Scene like that of a Bug's Life?

Hey guys, i’m trying to make a scene inspired by a bug’s life where you have a small subject of interest and in the background is a large tree (like that Pixar tree at the end credits of the movie)

When I make a full ground and put my camera from below it’s covering my camera so what i had to do is adjust the ground so that the camera is like at the edge of it (is this the correct way? or is ther a better way like may be changing the camera setting ?)

Also can you recommend tips or tutorrials how to make a bug’s life scene look better?
