help with housing

Last midnight i got some ideas to house and started other playthrough. The first hours got me really excited and i builded non-stop, but now i'm completely out of ideas for decoration/do the rest of the stuff

so just drop here what you think would fit with this pic: http://imgur.com/066FlOK

ps: the big hall will be like an trophy + armour room (idk if it's big enough)

ps2: i'm planning of change all wood to gray or red bricks when i get more resourses, i'm just thinking if it will be too strange, or will fit more the style
