With your original pictures - I agree with larger rug. But I don't agree with comments suggesting the rooms are monochromatic. They are lively indeed. I think you are just missing some accessories! Art work on the empty walls - even just a single large dramatic piece is in order. In the bedroom on the white wall, in the living space behind the sofa, in the greenish bedroom behind the two beds. Those are instant areas where you can improve. But I think your spaces are lovely and well put together. Also I agree with the comment about table lamps - some of those would really add something, and your coffee table looks so empty - maybe just one gorgeous bowl, or stack some books. These rooms are 90% done in my opinions, just need a few finishing touches. Some of my rooms come out like this because the clients are not willing to pay for those last few finish items or feel they can do that part themselves...

OK... but the wire wont be lower as it is fixed now. The wire in the pics below is the wall facing each other. They were leveled on equal height but the beam on one wall makes it seem a little above. But i think you guys are absolutely right that up and down lights wont look good there. I think you are right about down lights lessismoore. Would it look good if i go with two different lights on opposite walls??? it would look odd right.

I am assuming you haven't finalised your wall colours and colours of any other fixed elements. In case you have finalised your color scheme you would need to see which of these colours blend well or complement with that scheme. Assuming none of this info is available, then you could look at the neutrals which go with all colours. The white tile and the 2 colours at the end would be preferable. If you want color on the floor as well as drama, you can choose from the 2nd options from both sides or even the 1st from left.

two basic issues your room floor is dull is that floor to floor carpet if yes then add a a smaller area rug under your table to get splash of colour, alternatively if you dont want to do that then add some colorful wallpaper behind the sofa. Where you have the table lamp add something taller like a modern floor lamp or a tall spread out palm plant. Take the table lamp and add to a side table if you have one. The second biggest issue is that you have a lovely modern sectional sofa and then you have paired it with a very traditional and very high coffee table that looks like it has marble inlay work done (cant make out clearly). This is not a good pairing. The coffee table is the right size but get something modern and a lot lower, a general guide to this would be one inch to 2 inches lower than the seating height of the sofa. As someone else mentioned an Ottoman that can serve as a coffee table in an alternate colour will also work. Paintings and wall art is something you can experiment with but unless you do something about the coffee table the room will continue to look odd in my opinion. Also some more shots of the room will help us get perspective.
