Its a cute little house, just a bit barren with all that brown grey stone. I think you really could do it up yourself. Needs rugs and flowers and vases and tables and bookshelves and such. Oh and light sources. I'd probably move that bear rug inside, wet bear fur smells terrible. You could dress that dress form up with outfits (some pics from Maiden' Chinas site here:
Decoration Kits) and add a second one, do shelves with cloth and leather and benches, etc.
BTW I think they are coming out with new soulforges that are much smaller, so keep in mind that will free up some space if you decide to get one of those in the future.
If you decide to mess around with carpet keep in mind it's horrible to try to place stuff on it afterwards, so make it the last thing you do. Place all your deco as you want it, make sure each and every item is raised up at least 1 time, then you can put down carpet tiles.
Don't forget wall features like tapestries, paintings, and wall maps etc.
