The wood is beautiful. To me, the wood has an oriental-Japanese-inspired vibe. This wall's paint is nice, if your can match. Here's a method of choosing wall paint: http://www.lindaholtinteriors.com/2011/07/testing-wall-color-101/ Can you keep just the curtain panels and remove the sheers? At a later time, a non-patterned curtain panel the color of wall. I saw the art and I think it is OK, but not for this room. Perhaps in a bedroom? I don't understand the theme you have going? Giraffes? Clocks? If you like clocks, remove the giraffes and buy something like a large round wrought iron "clock". Note also the rug, pillows & throw as inspiration for your room. Perhaps the TV console in a lighter tone wood like their end tables (your room = too much black).

You have a nice geometric, somewhat masculine look going here. I would play that up. I don't think you need to change the wall or carpet color as they seem to be a nice neutral background. Are they cream? is the purple more plum? and is the blue more of a steel blue/gray? The furniture is chocolate brown? I love the striped pillow on the chair. I would layer a wool steel blue/gray area rug and then play up the blue/plum in the pillows. A wool plaid or blue gray herringbone in a couple of throw pillows (replace a few of the solid color pillows) could help to pull it all together. Kind of like the colors in the picture of this bag. Adding brown leather cording would be a great compliment on the pillows. (Not sure the area rug in front of the TV is adding anything)

Do you live in a warm country - then you might want cool colours: pale blues, greys or greens. I would leave your bathroom as it is - love the niches. To add some cosiness to the marble floors, find a nice cream carpet and cream furniture and then use this as your base for colours that you like. BTW what colours do you like? What inspires you. When you travel or go out ... what is that makes you happy? This will help

I select these colours with the help of other houzzer and expert professional advice and discussion. I also got help from colour paint catalogue. Is it looking good or not? Is there any problem with these colours and their combination. Please guide me in this regard.
