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.

Here's an idea for a small bar in a corner that you could close off with beautiful draperies. The second photo shows a pretty bar cart which could hold the necessary items, and the third photo is of a simpler butler's tray.

I bought 'interior designer for iPad ' for a quick sketch tool - it's quite easy to use - you can import images and build your walls over them - the only downside is it doesn't let you see where the windows are on your import to get them in the right place ( if you haven't got the full measurements) but if this is for you own home - that won't be a problem ! The kitchen design bit lacks decent corners - but as it as incredibly cheap - but gives you plans and walk throughs and perspectives - it can be forgiven for it's few down points ! You can import photos of your fabrics too - to give a realistic image of sofa or rug colours etc ... Have added some pics of a lounge I was playing with !!!

I would do gray walls and just make sure it has the same undertone as the tile I often paint the ceiling the same as the walls if going with a light color or if a little darker for walls I cut wall color 50% for the ceiling. I have a gray and mostly white LR and I have walls a color called Vancouver Day from C2 I then add color for different times of the year with pillows and a few accessories The wall behind the sofas I just painted in a purple from one of the pieces of art and I love it.
