I like the ceiling insert and the floor. The ceiling repeats the floor color and the ceiling design adds some interest. The rest of the room, I do not like.

I think it is perfect

HI! I love the floor. The ceiling is nice. I really don't like the furniture and the red wall. I would have chosen this furniture. But go on! It's cool!

I love it. The ceiling is so beautiful and unexpected. You must be very talented.

I like the ceiling. I think the hanging lights are too fancy and distract from the ceiling decor. A simpler light would look better or sticking with the canned lights you have.

The walls have too many big, black things on them. It's hard to tell if they are windows with shade --- in which case I'd pick something lighter, perhaps to echo the ceiling, TVs (how many do you need?) or what. I'd consider a big piece of statement art in the place of at least one. If you're on a budget, get a large, high quality photo in the right colors, you can take it yourself. Sepia and black architectural might work.

I like more color and more natural light. You may have closed the shades for a better picture, so it's hard to comment on the light, plus windows are a feature of your room, not exactly a decorator's choice. I would consider how to get a few small pops of color in, pillows, flowers, candles, maybe even a runner rug along the right wall.

If you are doing this as part of a portfolio, the entire ensemble would look more welcoming with a few touches like someone lives there. Something on the coffee table, for example. A few books and a candle. A tray with tea things, a vase of flowers or basket of fruit. Pick one or two things and make it composed. You see this a lot in designer Houzz photos.

Here's an example, you note this picture would be a lot more stark with an empty table:

Looks European?

Thanks so much for all your feedback.The concept while designing this living room was to keep as simple as possible but with some bright colors and patterns , as the client needed something vibrant and colorful.The tv is placed on a 3D wave board with minimal white color to contrast the environment.The diffused light effect on ceiling gives a warm surrounding.Thankyou.

like it in general, in details, I would change ceiling pendants to something less fancy (actually not needed any fixture, but... it is there now), add big area rug. Didn't get what are some black and brown (left side from TV) squares, roman shades in different colors?

Besides tv unit the brown color square is the roman blind for covering windows

European?? Really?? Uhm..

Too much lines, colors, bling and way too much direct (and blue led) lighting. Does not feel cozy and homey to me. Plus the tv would be better off on either a dark surface or a wider white wall.

Edgy in a bad way (as in not restful). Can see what you are going for but it never actually coalesces into a harmonious whole. I would give it a b minus at best.

More than a LOT going on in the room. The eye needs a place to "rest" and this makes it hard to know where to do that. You are drawn to look "everywhere" rather than having central pieces that are complemented by (rather than competing with) other things.
Lighting and light sources are all quite harsh with no layering. Recessed ceiling treatment that is echoed in floor below is nice...but then competes with lighting. Walls have so many heavy/dark areas that it's confusing. TV is not well balanced with white space behind, nor media console below. The space ratios are not consistent in the room.
The color scheme definitely has potential, but everything feels "hard" with nothing soft in the room.
