Makeithome- Love your inspriation pictures! I have one question. Is there a bathroom and an office, between the kitchen and breakfast room? Do you think you'll eat there more often, or in the dining room? Also, have you thought of putting a french door in the living room, to separate it from the sun room. Depending on how you use the sunroom, this would allow some sound control and give you a great place to put an extra chair or Christmas tree, when necessary. It's nice to have some comfy dining chairs that you can use in the living room, for extra seating, during the holidays. And, it's easier to use a room, when it can be closed off (even if only temporarily). Sitting in front of a french door, is easier than sitting in front of an opening. I think I would turn the sunroom/breakfast room into a combination tea room and library, but that's just me, since I love tea. (LOL) It would be a great place for a few plants (maybe some herbs) and a hutch with fancy teacups and teapots. The front part of the sunroom would make a nice library, with a few comfortable, upholstered chairs for reading, etc. Bookshelves are always a good idea. I like the idea of closing off the living room window and adding a bookcase, with more bookcases on the other side of the wall. Once you decide how you're going to use your rooms, I think it will be much easier to choose paint colors. Think about how you want to use your spaces and everything else should fall into place :)

Holly, I’m pretty much agreeing with @Maureen ideas. I see a nice blue floral on left wall of red console & another floral with reds on right wall facing console. How about try moving that smaller red one on right to wall above yellow chair (which we think should be moved). if you have other smaller art that you can put with it to make an arrangement which is the same general size as blue art on left, then you’ll have the balanced look @Maureen suggests. If the empty corner is too empty, @Aneisa Ahmad suggested floral on floor - maybe an interesting red pot with Asian flair & some greenery would look good, tie into red console & not visually block the doorway.

Actually the beam is no lower than the headers of the doorways. It looks like it's wrapped in drywall so you may be able to make it a bit smaller depending upon how they framed over it, but it the absence of something like that I think I would paint it either the ceiling color or the wall color and ignore it.

Depending on whether you are a gardener or not, I might get some railing baskets to fill with annual flowers. If you wouldn't really sit out there (if you don't need chairs and table), a small bench placed straight ahead when coming up the stairs might look nice and someone could sit there if they wanted. A larger mat or maybe a mat on the tile at the door and a larger outdoor rug where the mat is now.
