One more general suggestion, when using step hedges / walls, I find that you can sell the 3D illusion better if there is at least one space of separation between the top hedge and any items on the top level. This makes the top level of hedges resemble another step rather than a wall that sits above the top level.
To better observe this, in front of the Kwik-E-Mart, see how it looks if you remove the 4th line of cobblestone walls.
And behind the church, try moving the 3 closest trees on the right left and back one space and compare how it looks to the to the trees farther down.
