I really like clean, uncluttered spaces. After all as you play with your sim/family you end up having to buy items that soon fill up any empty space anyway!
I love the shape of your house, it's interesting to look at with the balconies and roof line. I also really like the entrance way, a great idea to have the coat/shoe area.
The only thing I'd suggest is to centre your dining room table to the two windows to the right (in the down shot) and move one couch back and the other one that backs onto the table forward so the rug sits in the middle perfectly between the tv and 2 couches. Maybe add an occasional square table at the meeting corner of the couches with a lamp on it.
Small details that make no playing difference just visual harmony!
Are you going to put your house on the exchange? Hope so!
