I like your decorating sense. All ya need now is an elk mounted over the fireplace. A guy I bought a broodmare from had one that was gorgeous, but it was WAY too big for his house. The base of the sucker's neck was about 5 inches off the floor and the antlers touched the ceiling. He also had a full body black bear mount, a huge timber wolf and a cougar. This guy was SERIOUSLY into big game hunting, but he was about to run out of house to display them in.
We have a friend like that.... had to move it to a whole trophy room. Course most of the room was taken up by a half-mount bear that came out about 6 feet. He had shot the AZ state record black bear, so I think you have to do a big mount for that :~D
Like you said, an elk head is large. When I get time to go home and stay there I hope to spend some time collecting furred, feathered and finned animals to adorn the walls. Remember that pic of the goose? He's in the freezer waiting to be taken to the taxidermist.
