Easiest to start with new drapery fabric in a pattern you like. THen pick up the grays and tans from it.

First get rid of everything you don't want , then paint all walls white. That will help you imagine what you want where, right now all I can see is coral, not good since it is one of my most unfavorite colors. If you rally strip the room down you will know what to put back in. If you are wanting a more modern look the drapery will not work as is. The little pointy things over the doors and window have to go. I can't tell the color or print of the drapes but i would guess there is some coral in there too.This is such a pretty space please do it justice.

Draperies are the first to go . came with house. Do I Continue with long curtains and pull back .

Get two great ceiling fans to replace the little chandelier. Color is too formal check out ben or sherman they have great variations on neutrals.
