Mostly I go on how a house "feels" to me, not just the way it looks. I seldom have enough "construction-eze" to be able to express technicalities. So, Dane, your house, whatever the style might be, is going to be terrific. House number one "felt", empty, barren, almost like a cartoon house. House number two felt wonderful! It felt warm and welcoming, and despite the gingerbread being actually missing, there was an illusion, or an expectation, that it was there. Just not visible. The colors were great and the stone work/masonry on the exterior were perfect, imho. House number 3 felt like it was looking down it's nose at me. At was cold and off putting to me, at least in the front. So if the three versions of this house were on the market, I'd buy number two, the middle rendition. I think part of it was the landscaping. Total lack in version one, except for those oh, so, austere trees, lovingly cared for in version two, and just not quite right in number 3. The bougainvillea didn't seem to go with the jumble of shrubbery and the many little fences in version 3.
As for Lynley and Ausette. Ausette I've downloaded your house and love it and have already placed it in the new town I'm developing for a new legacy/dynasty/Simstory. What used to be Sunset Valley will become, Happy Valley, or something similar with pretty much all the buildings being ones people here have created or remodeled.
Lynley, I liked the roof line in your first rendition but the second one is ok too. I love the color of the house. It looks like one I've passed on my way to Costco and I admire it every time I go by. It's a historical house here and you've caught the feel of it perfectly. I love the fact it isn't just another straight line, or box, or L shape starter home. It's charming and if you put it in the swap shop it's going to be in Happy Valley. Don't worry overly much about the entire decor as folks will change it to suit themselves anyway. However, I happen to like what you've done. The only thing I would do is take away the easel and add a small bed in that room, or a crib.
