You have a beautiful home! Okay, from what I can tell is you have too much furniture in the room. If you have a couple of teenage boys, then keep the floral sofa for now, if not, it probably should go. lol Once you take that sofa out you can then figure a better floor plan for the leather furniture. I like the arrangement but I'd scoot the leagther sofa back to the sofa table. And maybe add a coffee table in front of the sofa. You will still have space for walking and for your little one to play. Maybe a painted wood coffee table to add a bit more color? I would take the end table/lamp out of the room, the one between the chair and wall, and add a floor lamp in the corner. With those pieces gone, you can turn the clock to face the TV, but centered in the small wall space near the stairs. Rooms need to have a bit of airiness to keep from feeling crowded/claustrophobic. I've been in your situation before and it was hard getting rid of pieces I liked, but once I did we felt a lot more comfortable!

I love the clean, uncluttered look of your home and you've made some great furniture choices. My first thought, though, is that I would try to rework the sofa/sectional placement. It really is unwelcoming looking to me to have the back where it is facing a wall, when it could be oriented to look into the room and out the windows. It seems like if it were placed in the corner under the stairs that it would feel open and invite you to come in and sit. I'd hate to be cooking in the kitchen and have the family or guests with their backs to me. If you are having a TV in another room close by, do you need one in that room, too? If, so placing a 70" unit will probably only work as you have it. But, to me, it's not going to look like a living room but more like a movie theater, which is fine if that's what you're going for. It seems like it won't be a cozy conversation area, though. I might actually flip the rooms and put the dining room where you have the sofa now. I was looking at lights used with dining rooms and ghost chairs and saw this, maybe would work in the living room? Kind of fun. don't know if it would look as good without the colored walls though. And I thought something like these were interesting to consider for over your table:

Holy moly, so many great ideas and feedback here. Thank you all so much! And boo - I spent a lot of time trying to decide on window coverings for those weird skinny windows, LOL. As least they're cheap JC Penney shades and won't hurt too badly when I replace them. I like the dark wood trim and didn't want to cover it up, so that's why I chose those and not curtains. But I heard everyone loud and clear. ;) Storage definitely is an issue with this house - there's exactly none. All the storage space was sacrificed for a big open feel, and even the closets are postage-stamp size. Thus the big old coffee table thing (storage!) and the entertainment center (storage!) and the end table (you guessed it, STORAGE!). I love the Besta idea, though! Didn't even know something that cool existed. I am worried that placing the main seating against the half-wall will put the seated person too far from the TV; I do a lot of gaming so I tend to sit closer for full immersion. I was considering moving the seating way closer to the TV, which would create a big space by the half wall, and then putting a narrow table or something back there, i don't know. I'm so terrible at this stuff, that's why I'm so glad Houzz is a thing! A sectional, huh? How does one find a sectional that doesn't scream 80's media room? Off to google I go... :)

Could you center the couch w/ the window and move the chair (angled) to the opposite end? That way, someone could see the tv from the chair as well.
