It's looking good, but I still see a couple of mistakes. I've listed them out. Could you edit them please:
As you can see, the roof is out of line at the right side, the vents are in the wrong position, and if you look closely, all the windows are a couple of pixels too far left. I don't mind how long it takes, but could you fix it please?
Oh, and could you send me a link to the Tile Inserting tutorial that you use?
