I disagree with the idea of variation needing to be used. It really depends on what you're going for here. At the moment it seems like a very strict and stern environment. Perhaps a man who has lived long and been through wars lives here?

The Greyjoy's come to mind. Specifically Balon.

Keep at what you're currently doing, as it looks great.

(Also I mean no offense in saying it looks like an old man lives there. I mean, come on - The old man is Balon Greyjoy. That's a compliment. xD)
