In my opinion, a cuckoo clock is a very detailed design, but you say you want a simple design for the room. When you say simple, are you thinking of no wallpaper, no wainscoting, and no accent color on the walls? It seems as if dark orange is a color you favor. I see it in art images and in your curtain color. If this was my space, I would paint all the walls one or two shades lighter than the beige of the sofa to keep the room as bright as possible because the room has no direct sunlight. I would paint the ceiling 1/4 (one part wall color to three parts white). I would use a satin or eggshell paint instead of matte, semi-gloss, or high-gloss paint. I see some discoloration on the wall behind the sofa where the brown color of the sofa frame has worn off onto the wall. I suggest attaching bumper dots or strips on the wood frame of the sofa (similar to the ones used to keep cabinet doors from making a lot noise when they are closed quickly). I would consider painting the sides of the column with the cuckoo clock brown to match the clock. I would do this to call attention to the clock. I would remove the orange curtains and replace them with floor-to-ceiling length draperies hung as close to the ceiling as possible to make the room seem larger and taller. I would change the drapery color to match the walls, perhaps in a muslin-like fabric, which is a casual fabric. I always take my art to a professional framer. I have conservation matting and museum glass used for my art. I would have the three images you have rearranged as a collage in a very large single frame with medium to wide matting between the images. I would have the mat and frame color(s) enhance the images, even if it is a color I might never have thought of on my own. I would hang it above the sofa. I would use the orange drapery fabric to make throw pillows for the sofas. You did not attach a photo of the flooring in the room. A medium tone floor is easier to keep looking clean than a light floor/rug or a very dark floor/rug. Other "Houzzers" will give you completely different ideas. Use the ideas YOU like and enjoy your home!

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).

well it isn't going to be white or cream or a light colour if you have three dogs and two kids! But as Taylor said, all depends what you are looking for.

Try microfiber as it is easy to clean and take care of. If you are worried about stains, try an indoor/outdoor fabric like Sunbrella. I recommend Ultra Guard fabric protection in lieu of Scotch Guard. Stay away from loops and chenilles if you are worried about your dogs and their claws. Solid colors tend to show stains and pet hair, so try looking for patterns or multicolored fabrics. Hope that helped!
