What photos are before and what are after? Panoramic is distorting room(s). Mirror looks like it might be nice over fireplace mantel. Mainly de-clutter and thin possessions as you said.

furniture is too bunched up in the living area. move them back towards the window. edit knick knacks to a minimum. should look like a hotel lobby for staging. remove personal effects. good luck.

I wouldn't put tables in front of the windows,you make it look smaller. For staging I would remove the darker chairs all together,and one of the small round tables. The object is to make it appear spacious. You will have more room to move the remaining furniture that way. And add some bright colored accents, just for interest!

Thank you all for the great advice. It was all so helpful. Here's what I came up with. It's still a work in progress as I'm still decluttering and moving things around. So feel free to let me know if I'm on the right track at least.
As for the awful ficus trees, unfortunately they are great space fillers and for lack of anything else I will have to use them until I can find something to put in their place. Family pictures will be removed as we get closer to putting our house up for sale.

why not position the small couch straight along with the window (set a foot away from it)?

The short curtains and rods all need to go and you should remove everything from the walls and surfaces (especially window sills.) Repair the holes they leave and repaint if you need to. Is that a recess for TV above the FP? It should be used for its purpose so prospects don't have an "I wonder what that is" moment. Do not decorate walls above the door frame level. This leads prospects to worry about what they could do to that area. It is not where you and your stuff live, so it needs nothing. Clocks are poor decor but might be seen as useful in the breakfast area where people are eating before heading out to school and work. Don't use mirrors unless they have a chandelier or fab view to reflect. Art works better, but keep it to a minimum and of a nice impactful size. TV tray tables, plant stands, skinny single purpose tables, low footstools - all get interpreted as clutter - so bust them out! Switch your chair and hassock with the loveseat. Use furniture as purposed. The end table at the FP area should go between the chairs as designed and not be used as a coffee table. Same goes for the buffet under the window. Once the curtains are gone it may fit to the right of the window, but if you want to sell it with the house, use it as a buffet in the dining area. You are setting up a story board here and each vignette must tell the story you want the prospect to get. No room should be a dining/office/library - that will confuse prospects. Each room or area must make a single defined statement about its purpose. And all of it should look clean enough to eat off of. You'll probably feel like the room is bare. When that happens, you've just about got it ready for market!

Ok trees still have to go. You don't need space fillers! Move the round table that is next to the chair where the tree is next to the sofa. Put a lamp on it. Still need a bright rug too. Getting better!
