Thanks for the feedback! I know a sectional will be limiting, but I can't seem to make anything else work. The doorway to the left is to the kitchen, that isn't moving. Anything I put in front of the window needs to leave a walkway to the door. Same for anything on that wall next to the kitchen. If I put anything there that is not against the wall, it needs to be out enough to have a walkway to the kitchen, which puts it too close to the FP/tv. Moving to a couch and/or loveseat is an option. I just can't seem to make that work. It always looks off balance and odd due to the kitchen doorway needing clearance. It's entirely possible I just haven't found the right combination yet. I would definitely consider adding some recessed lighting. If I end up putting in a built in along a wall, it would definitely need a light above each side. The only light currently in the room is a flush mount ceiling light centered about 3 feet in front of the window at the bottom and a floor lamp next to the 18 inch support column. Hard to make it anything but better from there! Additional thoughts/suggestions welcome! I have a really hard time with stuff like this. Lucky for me I found an app that let's me play with furniture, sure beats drawing it out each time.

Measure out your space to see how much usable space you will have for the furnishings. A sectional might or might not be a good option for you. As you shop gather dimensions of pieces you like then use tape and place it on the floor so you can see how it will look space wise. As mentioned above pick your focal point. Your fireplace is so nice it seems that you should work around that.

Is any of the furniture staying? It looks as though you have the bulkier (white) chairs as you enter the room. Have you tried switching them? That might give entry room by the couch and fireplace.

The wall doesn't need decorating. Your room needs drapery to the ceiling, perhaps in a pattern to add some interest to the room. Your current wall decor on the left is too small for that wall. I boosted the size.
