Beautiful and playable castle. I like the technique for the dungeon's roof, the interior (particularly the last floor, with the man carrying a map) and the stained glasses. Completely looks like a castle for kids (that we are still ).
I've been looking forward to seeing more of your stuff this year. Another great creation, I am really liking the color combination of the dark gray and dark tan. I also really like the roof technique, I don't think I've seen that before and the "dovetail" effect with the tiles looks really good. The courtyard looks awesome, and I especially like the details on the front of the keep. Good luck in the contest!
