I like second plan! That space will fit the wardrobe perfectly. Take all colors from the art. The colors can be lighter or darker than the colors you see in art. Take "Venice" with you to paint store and they might be able to help you choose good colors. Idea: paint four walls the same and see if you like that. If you feel the room lacks interest, then paint the accent wall. Choose a pale green that harmonizes with "Venice" and a darker green accent. Yellow + red accent White + blue accent

If you love that wallpaper, use it in bathroom. Not really right for behind bed. I would go a drum style chandelier. In a silk pale gold. Your bed looks zen or Asian to me. I love it. But, you don't. Need to much with it. Keep it simple a more formal drape on windows, color would depend on wall color and bedding. I'm thinking a dramatic peacock satin. Use a lighter same tone on walls a rich teal. Ceiling can be gold leaf. With alight that cast shadows on ceiling at night. Then your wall paper will tie in. Furn should be mirrored.

i agree with lighting trends on the peach ,here are a couple of palettes to choose from note your lighting will accentuate the mood and can give the hue you want , but definitely go for a neutral , the colours are from sherwin williams, benjamin moore , behr , and kelly moore

The room has exquisite bones: the windows, flooring and decorative crown molding. If simplicity is what you want but with a bit more personal taste, I suggest the following: 1) paint the walls white that has a soft, warm undertone such as Benjamin and Moore's moonlight white or Dove. (Or try any good paint store for help on picking the right white color.) Paint the molding a stark white with an egg shell or gloss finish. 2) keep the bed covering as is. I love the warm colors and mixed patterns. If you do want more comfort, yes add a thicker mattress. Can you get a fabric similar for the table top? Or just remove the fabric from the table top, painting or stenciling it with a similar pattern. (see #5 below for where to look for stencils.) 3) Move the table to the head of the bed, add a modern lamp and lots of books or other meaningful, personal items. 4) Add a comfy chair or as suggested above, pile lush floor pillows where the table is, under the window. Use complementing or solid color fabric on the floor pillows or chair. Add a small table with more lighting. (See my most popular post on Floor Pillows. Towards the end you will see examples of suitable floor pillows. Or just do a search here on Houzz and the internet.) 5) Make a dramatic statement above the bed with a very large painting. Select with care based upon your personal taste: abstract, minimal but with a hint or some of the colors found in the bedding fabric. It doesn't have to be centered, a little off centered will do since there appears to already be something on the wall above the bed. Do add a soft art lamp above the painting. (If you don't have money for the painting, purchase a very large canvas, take your time and create it yourself (collage it, play around with paint on paper before adding it to your canvas, stencil it, etc.--but have fun and make it personal) Here's a great place for getting a wide range of designs for stenciling: Cutting Edge Stencils. Note you don't have to take the design all the way to the edge of the canvas! 6) Add a small (wool) flokati rug in front of the bed. Get the kind that comes from Greece, it has long-fibers and a plush pile. These rugs are to die for when it comes to comfort and texture--and they're inexpensive. Take a look and if you like it, be sure to get wool: Flokati Rug.Net. These ideas will give you lots of varying textures to get rid of the boredom; contrasting colors for depth and drama; play up the wonderful architectural elements already found in the room; personalize it with what you love; and still, keep it simple and beautiful. Use soft lighting. Good luck!
