It looks really good, but judging from the pictures, you've scaled it wrong. That's why I think people are talking about it "not being a mansion".
I'd say the floor height should be around 9-10 bricks, at least twice a player height since if you look at the first picture the people are about half the height of the first floor. And everything else should be scaled up like 150%, and I think it'd look better and be more accurate.
