I have a tattoo running vertically down my spine, looking for placement for my next tattoo! Help =]?

Okay the one I have says "golden slumbers fill your eyes", If I'm lying on my side you can read it. My next tattoo is of a gypsy girl looking straight on with a bird of paradise on her shoulder and some really great flower type things around it. About the size of a postcard, and a 'cameo' style shape. Where to put her? Id like it on my back but it might be too much with the other tattoo.
