Here are some other things I really love for your room, but I couldn't put the pictures into mood boards because of the "non-white" backgrounds. Check these out and let me know what "grabs you"! Don't let the sources scare you. I've been known to find the Pottery Barn look "on the cheap".
Bedding from Overstock.com. Love the "spice" or "black". "Spice" would go well with your furniture and we could repeat the color in accents. Black would go with the black/cream mood board.
Pottery Barn Bedding (this is a quilt). Color is mocha.
Another quilt from PB. Same color - Mocha
Organic Matelasse Bedding from Pottery Barn (I see this look at TJ Maxx, etc too) Any of these colors would be nice.
Pick-stitch cotton quilts from PB. Love the blue, maize and green!

Floral "without being fussy" area rug from Pottery Barn
Parchment shade lamps
Window style mirrors
