This MOC is great! I love it! I really like the way you did the edge of your dormers and the way you finished the top row of roof slopes at the edges. The interior looks very nice. The stable makes good use of the Dragon Fortress pillars.
A couple problems I have with this MOC, two of which can be seen in this picture: http://www.brickshelf.com/cgi-bin/gallery.cgi?i=808439
: The first (minor) one is the wooden bar on the door; I don't think it is very affective on the outside. You would have trouble fastening it from the inside, and the enemy would have an easy time breaking it. Two, the fireplace needs much more foundation; as heavy as it is. It would needs some pretty heft beams under it since it doesn't go all the way the the ground. The only others I have are that you should use some more black and yellow in the from to go with the door and the arch. But still great MOC! Keep it up.
