The mirror being bad for feng shui is unavoidable because directly across from the door when you open it is a floor to ceiling mirror closet :( To the left of the entrance door is the blank wall, and you turn right to the hallway. Also, this is a 9th floor condo. It's 1150 sq feet, but the rooms are all narrow (including the hallway). So I'm trying to make it bigger. I don't want to add a coat rack because even walking around the small vase makes the corner feel tight. Its also redundant, because of the double sliding door (mirrored) closet across from the entrance. Which people will look into, unfortunately. But it seems everyone is against the mirror, so I will do some mock ups of just pictures/art to see how that looks. I was also trying to get more light into the hall, as it's pretty long and can feel dark/claustrophobic. Maybe I'll look at better light fixtures.

You can just add some styrofoam blocks behind a large piece of art (one that fills the niche) to move the art piece forward a bit, so it doesn't look like it's in a hole. You could stick them to the wall and hang the picture from hooks in the top of the niche instead of from the back.

What are you willing/able to do? What, specifically, are you unhappy with? Are you considering replacing the furniture? Paint the walls? Without more information it's difficult for me to make suggestions. However, I'd strongly suggest moving that chair away from the draperies/window. And also change the paint color. Is the room as small as it looks in these pictures? If so, that furniture, in my opinion, is far too large. When you say "Beautify my living room again" (again being the word I'm referring to), what did it look like before when you considered it beautiful? I think you've got a lot to work with. It would also probably be a good idea for you to post this also in the Home Decorating Forum.

Ok good - I hate that furniture but didn't want to say anything! It is a fantastic room but it actually looks like it might get northern light? It doesn't seem super bright. The dark wood isn't helping. I'd rip up the carpet and but down light wood floors and add contemporary furniture with warm elements but definitely paint the molding. Ask your husband if it was already blank, would he ever want to add molding like that? If the answer is no, then you don't need to preserve it.
