Hey, you have orchids too (...wait, are they real...?) Dolls and flowers are a great combination. Looking forward to seeing more of your photos. You have some nice ones on your Flickr.
Backgrounds... well, the less "busy" the better, unless the background is part of the scene. Sometimes it's hard to find a good place to use for a photo. I've tried hanging shirts for a plain backdrop, and I bought some batik-like fabric which occasionally works. And if you can adjust the depth of field on your camera so the background is out of focus (or at least make sure your autofocus is on the doll) that helps too.
Keep taking pictures and having fun
