I love that bed! you should totally make some/get some drapes for the bed, something semi see through could be nice. You could put those cool bead accent things (you get them at the store, something like 2 yards or so) that can be put on lamps on the bottom and tops of the curtain to spice it up...Uhm, get some pillows from a thrift store-well, maybe-and make some new covers for them.
I think you should get some frames and totally put up those picture! I would reccomend dark wood frames that match the bed.
You should get one really big one and then assorted sizes and put them all over. Plus you can always take more pictures together
and put them up too.
My boyfriend and I have pictures of marble sculptures up in our room from Paris. I am sure you can find some good ones on-line or on this site from someone.
Since bedrooms are more fun when they are sexy or at least dressed up-in my opinion-you could get some wall sconces and put those around with candles.
Uhm, depends on what kind of feel you want your bedroom to be. You could go with an outdoor theme and put a bunch of ch'mas lights and ivy around your bed and then some sheer curtains to hide behind. Green could go nice with those colors.
I like that combination a lot!
Depending on the room size you could get one or two beside tables and put candles/lamps on those and dress up the lamps.
Hopefully some of those ideas help! Let me know if you want me to elaborate on anything more, just PM me.
Good luck, have fun playing with it!
