The moosehead will be wonderful. With that rock wall, it will be perfect. Living in eastern Washington (five miles from Idaho) moose heads are not that unusual. The leather and antler chandelier, will tie it all together. The other fabrics (especially some velvet) the lines you're choosing for the furniture, a little more carved detail (perhaps) on the wooden tables, (maybe a marble top, on an end table?) will all work with your rustic/romantic mix. Blondie- You have great taste, so go for it :) As for the sofa, check other furniture stores, but bring your picture. I'm sure there will be similar items that are much more affordable. Thomasville is not cheap, and Hemingway was their most expensive collection (probably still is).

If you want to exactly match your plan and make the house the way you want, then you should work closely not only with the workers and decorators but also with the furniture maker directly. Or find a good store selling furniture. By the way, you should also read a lot of reviews about the choice of furniture and its specificity. I can advise you to study the material on this resource https://furnishingsmaster.com/best-outdoor-rocking-chairs-review/ . This will help in your selection and your repair.

How far is the kitchen from the back of your couch? It looks to me that the furniture is too close to the high TV for watching comfortably. Can you pull your furniture back toward the kitchen or is there not enough space? How about putting your TV on the blank wall that your sectional is against and put your sectional in front of the window, turned the other way. Might cover too much of the window and door but if it was far enough away, it might work.

I would use the den as TV area with TV between the built-in bookcases. Then do a back-to-back arrangement with two sofas (they don't have to match) and a rolling sofa table between them. The one in the den would be the guest bed. When you have guests, simply roll the sofa table under a window and close the sliding door. As an office, place a desk facing the window if you need good light for online conferences, or put it on the wall if you don't do that. A rolling desk chair can move out of the way for the sofa to be opened. In the living room side, use a round dining table in the corner right of the fireplace. A coffee table 12-18" from the sofa and perhaps a pair of small scale upholstered armchairs in an "L" with the sofa, their backs to the window. Art, not TV, above the mantel.
