Needs some color!

I’d move the print to the right, to center on the couch, and pull the black leather chair out of the corner.

Same as flopsycat. Plus I’d add remove the shelves or try some color there. The little plant seems out of place. Maybe put that on the end table? Not sure.

I like it! The monochromatic color scheme is pleasant and calm.

More photos would be nice. Fireplace stone and tv to me is visually prominent. So the shelves and their items, even the lamp, seem too small compared.

Center art over sofa, remove small round table. Add a lamp and a plant to the square end table. Group the figures on the shelves closer together and add some books, a plant or two(fake if necessary). Take the plant out of the fireplace.

As mentioned, center art over the sofa. I think the shelves need to be reworked.

Remove those to skimpy shelves and either replace them with 3 thick shelves or no shelves and another piece of art the same size as the one on the right. The art centered over the sofa for sure and I would love to see a splash of color somehwere . Maybe in a pillow with a bit of pattern or something to give the space life I think a matching cabinet on the other side of the FP would be perfect. Monochromatic can be nice but also often borders on boring so even if you chose the blue from the art for the pillows might be a just that bit of color.

I like the monochromatic colour scheme. The only thing I would do to soften it would be to change the pillows to something softer - either replace the insert with a down one, or better yet a larger pillow e.g. 20 - 21". Something squishy. And pull the black chair forward - it has a bit of a "naughty chair" look in that corner. Maybe it's just the photo angle and it doesn't feel that way in real life?

Agree that the large picture needs to be centered over the sofa. The tall vase is squished into the corner. The plant is a good idea but too small to be effective. I like your shelves and I like the ladder people and the seated person. The other items on the shelf are too similar in size and colour and I'd replace them with something in a different colour and texture. Maybe something like a white glazed or metallic bowl. Or a woven basket. Or a hanging plant. One of those items might replace the tall vase.

Nice room, you're 95% there.

Color, please! Do it with pillows.

Also needs something lively: one tall plant and one shelf/table plant.

Color and Texture for this space.

@BeverlyFLADeziner wow!! what a difference! and these are really easy changes to make.

Agree with the others. It needs some color and life but that is easily done with a couple throw cushions and a plant or two!

I would paint the inside of the TV niche black to make that look more finished. I agree with the others that the shelves are too skimpy- I would prefer art there
