He's right, especially the blue ones maybe look a tad
too rough. But as a whole, they all look very sweet! Besides, they are a good basis to add further details like windows, doors, cables etc, so that you could texture an entire house with different variations of one and the same base texture, which would make for a very homogeneous look.
Just a little remark on the last one(s): As long as these textures start on the ground and end directly below a rooftop, the high grey stripe at the bottom and the small one at the top look very realistic and convincing. But if you put two of them over each other, you'd end up having a fat grey stripe running around your house between every two storeys, which is something you prolly won't see in RL...
Except for that little detail, both thumbs up!
