The level of detail you've managed to capture, both inside and out, is terrific. The floor technique is quite inspiring, though I feel like it doesn't quite flow well in this setting. Maybe because it's such a large detail for such a small floor. I can't quite put my finger on it.
Other than that, I love the rest. The bannister up the stair is nice, as are the shields and swords hung on the walls, and the use of several kinds of windows is done seamlessly.
Keep up the good work!
