Sorry for necroposting this, but I just finished playing LEGO Lord of the Rings(not 100% as Isengard was giving me grief and I despise LEGO Gollum for glitching up one level run
) and enjoyed Tolkein's story, so this inspired me to read this again. You are a marvelous story teller and I'm sorry that you weren't able to have an outdoor legacy due to Season's restrictive temperature mechanics.
Another house idea would be to have a hobbit hill, like Bag End.
Good luck on everything else you write.
EDIT: I also read the first post again and laughed at the first few lines. I suck at drawing but I would definitely put in a picture of a five-headed dragon with heart eyes squealing "GANDALF!!!" as Gandalf the white nurses a major headache. LOLZ XD
