Looking very good so far.
I think it was a good idea of you to make the floors higher, and the tudor looks much better then it did previously.
If you have enough tiles, I think you should definitely make the first floor grey, (or some other colour, as long as it looks like an actual floor, and not grass.)
Do you have a headlight brick in grey? If you do, I think you should replace the black one holding up the flag in front. I also think it would look better if you raised the flag a bit, so it's at least above the door.
Good luck with this, it's looking to be a promising creation. :-)
