Great! I'd start with the art work. Take a look at the photo below. It's a living room in a traditional home where I hung a contemporary piece of art in a grouping of others framed more traditional art. Then, on the sofa table on a classic old silver tray, I placed some whimsical birds, repeating the colors in the art. The patterned pillow on the sofa also repeats the colors.

Photos of the room would be helpful.
