Either dump the units or enlarge the structures.
Having both side by side reveals the simple fact that in order to go through the door even the children would have to get down on hands and knees to enter the structure.
When cobble or other laid stone type paths are laid the ground is leveled, or at is made true (say evenly climbing a hillside) they are rarely set lower than the surrounding land, and if they are passing the side of a hill somebody gets out the old pick and shovel and digs out the side of the hill to accommodate the road/path.
Image 1 and two the mid ground center you have a hill, part of the pathway (cobbles) is lopsided up the hill. Either extend the rounded bit further (across the path) or level off the path and lay in either stone or dirt - or build a retaining wall.
Enlarge the wall to match up with the gate.
Remove the dark fog, replace or use a different one.
Include a sky if you are going to have cameras as this low of an angle of attack.
If you are going to have this low of a camera make larger trees and smaller trees - diversify the heights, adding smaller trees around the bases of larger ones (seedlings).
