Awesome looking room! Like Bruno said, Dunno if you want to change this room, (that is, if you're going to eventually build another)...
But if you do, There's lots of room for great ideas in such an unusual designed room!!!
A few ideas... You could paint the beams flourescent colors that would glow.. Tons of room to hang signs & vintage style decorations!
More Ideas would come to me if I were sitting in there!!
Whatever you decide.. It's gonna RULE!!!! Have Fun!!!
