Thanks for clarifying that earlier comment, not sure how I got down the track I was on and see the issue he was describing straight away now.
I don't have plans to amend this set at the moment.
I agree that the bottom edge of the house tiles could use some more breaking up so it isn't so jarring, although I wouldn't personally use the solution you described. Still, you're welcome to make any edits to the set as you see fit.
Thanks again!
