@vancanuckfan86 I'm relatively new here, and this is only my opinion. I hope it helps.
Making up the built-in closet lends an air of verisimilitude to the place. It conveniently also creates the alcove for the shoe racks in the entrance way, so that's good too. However, the entrance to the master bedroom seems a little unnecessarily complicated: it might be better to carry on the wall of the closet to form a perfect 4x5 rectangle for the bedroom, so that one enters that room straight-on from a 2-square-wide hall instead of via a 1x1 corridor and a 1x1 vestibule.
The stepping back of the kitchen's floor pattern bothers me a bit. I feel that it should be (as with the master bedroom) a perfect rectangle; either 2x4 to exclude the back door, or 4x4 to include it. Alternatively, you could go 3x4 and move the back door elsewhere. I note that you seem to be using two single doors there instead of one double door, and I'm wondering why. There's a good set of double doors available already, nearly identical to what you're trying to set up with the single doors.
From the outside, the dining room looks like a sort of shed extension, and I was initially expecting it to contain the kitchen instead. If the kitchen were there, you could have a nice continuity of flow of living room to dining room, with the double doors (plus windows on either side?) aligned with the living room windows. I can see why you'd want the dining room off to the side like that, though: putting the dining area in an extension out from the main house means you can have windows on three sides around instead of just one. It might be a good idea, in that case, to get bigger windows just in that room, to really take advantage of all that exposure. (I'm a huge fan of the Narrow Outlook window, just so you know; if only it came in a solid dark brown! But there are other equally suitable full-height windows.)
This is just a suspicion, but ... is this house actually modelled from a real-life building? I see brickwork on the front facade, but clapboard siding on the other exterior walls. That's a thing done in real life, and I think it's because it's cheaper in real life to put masonry on just the one important facade that everyone sees than to put it everywhere. In the sims world, where clapboard is the same price (or is it actually more expensive? I forget.) the only reason seems to be to announce that there's something different about this one element here; to make a statement, if you will. I think this is the first time (although, remember that I haven't been around here very long) I've seen someone actually reproduce this, so congratulations there. Verisimilitude clearly means a lot to you, so good job on that.
You've been downloading houses for a while now, right? What do you like best about those houses, that you'd like to see incorporated into this?
